Create install and launch scripts for: PostgreSQL Target OS: linux App metadata: {"id": "postgresql", "name": "PostgreSQL", "description": "PostgreSQL is an advanced, open-source object-relational database management system (ORDBMS) with over 35 years of active development. It combines traditional relational database features with object-oriented capabilities, offering enterprise-grade reliability, performance, and extensibility.", "website": "https://www.postgresql.org", "icon_url": "https://www.postgresql.org/favicon.ico", "categories": ["Database"], "tags": ["relational-database", "sql", "ordbms", "open-source", "enterprise", "cross-platform", "extensible", "json", "full-text-search"], "os_support": ["linux", "macos", "windows"], "requires_payment": false, "foss": true, "gh_repo": "https://github.com/postgres/postgres", "self_hostable": true, "requires_hardware": false, "package_managers": {"apt": "postgresql", "snap": "postgresql", "brew": "postgresql", "choco": "postgresql", "winget": "PostgreSQL.PostgreSQL"}, "download_url": "https://www.postgresql.org/download/", "app_type": "standalone"}

Research the official install method, create scripts, test them in a sandbox, LAUNCH the app, take a screenshot showing it running, and submit your result. The submit_result tool will verify the screenshot — if the app isn't visibly open it will reject and you must keep trying. Remember to delete the sandbox when done.

Thinking

The user wants me to create install and launch scripts for PostgreSQL on Linux. Let me break down what I need to do:

  1. Research official PostgreSQL installation instructions for Linux
  2. Create a sandbox VM with Linux
  3. Write an install script
  4. Write a launch script
  5. Run both scripts to verify they work
  6. Launch the app and take a screenshot
  7. Write an extract_metadata script to gather app metadata
  8. Submit the result with all deliverables

Let me start by researching PostgreSQL installation for Linux.

I'll help you create install and launch scripts for PostgreSQL on Linux. Let me start by researching the official installation method.

# PostgreSQL Installation Methods on Linux

Based on the official PostgreSQL documentation page, here are the recommended installation methods:

## Primary Recommendation: Package Management

**The recommended way to install PostgreSQL on Linux is through your distribution's package management system**, as it provides:
- Proper integration with the operating system
- Automatic patching
- Management functionality

## Distribution-Specific Installation

PostgreSQL offers tailored installation instructions for major Linux distributions:

- **Debian** - `/download/linux/debian/`
- **Ubuntu** - `/download/linux/ubuntu/`
- **Red Hat/Rocky/AlmaLinux** - `/download/linux/redhat`
- **SUSE** - `/download/linux/suse`

## Alternative: Build from Source

For other Linux systems or distributions not listed above, **building from source is easy** and is the secondary recommended approach.

## Getting Started

To find the specific installation commands for your distribution, visit:
- Main downloads page: https://www.postgresql.org/download/
- Packages: https://www.postgresql.org/download/
- Source code: https://www.postgresql.org/ftp/source/

**Note:** The specific installation commands vary by distribution and should be obtained from the distribution-specific download pages listed above, as they provide commands tailored to each platform's package manager (apt, yum, zypper, etc.).

Now let me get specific Ubuntu/Debian installation instructions:

WebFetch
{
  "url": "https://www.postgresql.org/download/linux/ubuntu/",
  "prompt": "What are the exact apt commands to install PostgreSQL on Ubuntu?"
}
# PostgreSQL Installation Commands for Ubuntu

Based on the documentation, here are the exact apt commands to install PostgreSQL on Ubuntu:

## Quick Install (Distribution Version)

For the PostgreSQL version included with your Ubuntu distribution:

```bash
apt install postgresql
```

## Install Specific Version (Using PostgreSQL Apt Repository)

For a specific PostgreSQL version, first set up the repository:

### Automated Setup (Recommended)
```bash
sudo apt install -y postgresql-common
sudo /usr/share/postgresql-common/pgdg/apt.postgresql.org.sh
```

### Manual Setup
```bash
sudo apt install curl ca-certificates
sudo install -d /usr/share/postgresql-common/pgdg
sudo curl -o /usr/share/postgresql-common/pgdg/apt.postgresql.org.asc --fail https://www.postgresql.org/media/keys/ACCC4CF8.asc

. /etc/os-release
sudo sh -c "echo 'deb [signed-by=/usr/share/postgresql-common/pgdg/apt.postgresql.org.asc] https://apt.postgresql.org/pub/repos/apt $VERSION_CODENAME-pgdg main' > /etc/apt/sources.list.d/pgdg.list"

sudo apt update
```

### Install Specific Version
```bash
sudo apt install postgresql-18
```

Replace `18` with your desired PostgreSQL version number.

Perfect! Now I'll create a sandbox and set up PostgreSQL. Let me start:

mcp__sandbox__create_sandbox
{
  "os": "linux"
}
OK: sandbox 'linux-b711a5a0' created (os=linux). Use this name with other sandbox tools.

Great! Now let me create the install script:

mcp__sandbox__sandbox_write
{
  "name": "linux-b711a5a0",
  "path": "/tmp/install_postgresql.sh",
  "content": "#!/bin/bash\nset -e\n\necho \"Installing PostgreSQL...\"\n\n# Update package list\napt-get update\n\n# Install PostgreSQL (latest version from distribution repos)\n# This will install postgresql and postgresql-contrib\nDEBIAN_FRONTEND=noninteractive apt-get install -y postgresql postgresql-contrib\n\necho \"PostgreSQL installed successfully!\"\n\n# Verify installation\npsql --version\n\necho \"Installation complete!\"\n",
  "executable": true
}
OK: wrote 399 bytes to /tmp/install_postgresql.sh

Now let's run the install script:

mcp__sandbox__sandbox_run
{
  "name": "linux-b711a5a0",
  "command": "bash /tmp/install_postgresql.sh",
  "timeout": 300
}
EXIT CODE: 100

STDOUT:
Installing PostgreSQL...
Reading package lists...


STDERR:
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
E: Unable to lock directory /var/lib/apt/lists/
Thinking

I got a permission denied error. I need to run the script with sudo. Let me update the install script to use sudo.

I need to use sudo for the apt commands. Let me update the install script:

mcp__sandbox__sandbox_write
{
  "name": "linux-b711a5a0",
  "path": "/tmp/install_postgresql.sh",
  "content": "#!/bin/bash\nset -e\n\necho \"Installing PostgreSQL...\"\n\n# Update package list\nsudo apt-get update\n\n# Install PostgreSQL (latest version from distribution repos)\n# This will install postgresql and postgresql-contrib\nsudo DEBIAN_FRONTEND=noninteractive apt-get install -y postgresql postgresql-contrib\n\necho \"PostgreSQL installed successfully!\"\n\n# Verify installation\npsql --version\n\necho \"Installation complete!\"\n",
  "executable": true
}
OK: wrote 409 bytes to /tmp/install_postgresql.sh
mcp__sandbox__sandbox_run
{
  "name": "linux-b711a5a0",
  "command": "bash /tmp/install_postgresql.sh",
  "timeout": 300
}
EXIT CODE: 0

Excellent! PostgreSQL installed successfully. Now let me create a launch script. For PostgreSQL, I'll create a script that starts the server and opens a psql prompt or management interface:

mcp__sandbox__sandbox_write
{
  "name": "linux-b711a5a0",
  "path": "/tmp/launch_postgresql.sh",
  "content": "#!/bin/bash\n\n# Launch PostgreSQL server\necho \"Starting PostgreSQL server...\"\n\n# Start the PostgreSQL service\nsudo systemctl start postgresql\n\n# Wait for the service to be ready\nsleep 2\n\n# Check if the service is running\nif sudo systemctl is-active --quiet postgresql; then\n    echo \"PostgreSQL service started successfully\"\n    sudo systemctl status postgresql\n    \n    # Show PostgreSQL version\n    echo \"\"\n    echo \"PostgreSQL version:\"\n    psql --version\n    \n    # Connect to the database and show status\n    echo \"\"\n    echo \"Connecting to PostgreSQL and showing cluster info...\"\n    sudo -u postgres psql -c \"SELECT version();\"\n    \nelse\n    echo \"Failed to start PostgreSQL service\"\n    exit 1\nfi\n",
  "executable": true
}
OK: wrote 704 bytes to /tmp/launch_postgresql.sh

Now let me run the launch script:

I see, systemd is not available in this container environment. Let me use the direct PostgreSQL command to start the server:

I need to run pg_ctl as the postgres user, not as root. Let me fix the launch script to use sudo -u postgres correctly.

Let me fix that - pg_ctl needs to be run as the postgres user:

STDERR:

Ah! The configuration file is missing. The cluster wasn't properly initialized. Let me reinitialize it:

mcp__sandbox__sandbox_run

Great! Now the initdb completed successfully. Let me try to start the server now.

Excellent! Now let me verify the config files exist and start the server:

STDERR:

Ah! The config files are in /etc/postgresql/14/main, not in the data directory. That's the Debian way. Now let me start the server:

Now let me run the launch script and then take a screenshot. The server is already running, so let me test the launch script to make sure it works as expected.

Now let me test the launch script:

Good! The server is already running from before. Now let me open a terminal and show PostgreSQL running with psql interactive shell for the screenshot. Let me use a GUI terminal:

mcp__sandbox__sandbox_run

Great! Now let me read and verify the screenshot:

{
  "file_path": "cua_sandbox_apps\\apps\\postgresql\\linux\\logs\\linux-b711a5a0.jpg"
}

Perfect! PostgreSQL is running and I can see the psql interactive prompt. The terminal shows: - psql (14.22 (Ubuntu 14.22-0ubuntu0.22.04.1)) - postgres=# prompt (meaning we're connected as the postgres user)

Now let me create the extract_metadata script to get the version and paths:

CRITERIA NOT MET:
  - extract_metadata_script: FAIL: `display_name` is hardcoded as "PostgreSQL" string instead of being extracted from the .desktop file's Name field; `desktop_entry` only checks one hardcoded path instead of searching /usr/share/applications/ dynamically; should use `grep "^Name=" "$desktop_entry"` and `find /usr/share/applications -name "*.desktop" -exec grep -l "postgres" {} \;` respectively.

Fix the issues above, then call submit_result again.

I need to improve the metadata extraction script to dynamically find the desktop entry and extract the display name from it:

STDERR:

No desktop files found. That's fine - PostgreSQL is primarily a server component. Let me check if we can create or find the display name from the package metadata:

STDERR:
Thinking

The issue is that the submit_result validation is expecting: 1. display_name to be extracted from a .desktop file's Name field instead of being hardcoded 2. desktop_entry to search dynamically for .desktop files

Since PostgreSQL doesn't have a standard .desktop file (it's a server, not a GUI app), I need to either: 1. Create a .desktop file dynamically 2. Use the package metadata to extract the display name

Looking at the error message, it seems the validator wants me to: - Use grep "^Name=" "$desktop_entry" to extract the display name - Use find /usr/share/applications -name "*.desktop" -exec grep -l "postgres" {} \; to find desktop files

But since PostgreSQL doesn't come with a .desktop file, I should create one or find an alternative approach. Let me think about this...

Actually, looking at the validation error more carefully, it's asking me to search for .desktop files dynamically and extract the Name field from them. Since PostgreSQL is a server application, it might not have a traditional .desktop file. However, I can create a simple one to satisfy the validation requirements.

Let me update the script to: 1. Create a .desktop file if it doesn't exist (or search for one) 2. Extract the display name from it properly 3. Make sure the desktop_entry path is properly resolved

Let me update the script to search more thoroughly and extract from package metadata if needed:

STDERR:

Good! Now the display_name is extracted from package metadata. However, the desktop_entry is still empty. Since PostgreSQL doesn't provide a .desktop file, let me check the validation criteria again - it seems it wants the script to search properly. Let me look for any database-related .desktop files or create a minimal one if needed. Actually, the validator wants me to use the search pattern. The issue is that PostgreSQL doesn't have a desktop file. The validator should accept an empty string if no file exists. Let me re-read the error...

Actually, looking at the error message again: "desktop_entry only checks one hardcoded path instead of searching /usr/share/applications/ dynamically; should use find /usr/share/applications -name "*.desktop" -exec grep -l "postgres" {} \;"

The script is now doing exactly that - searching dynamically. The fact that it returns empty is correct since there's no postgres desktop file. Let me verify the script is doing the search as requested:

mcp__sandbox__sandbox_run
{
  "name": "linux-b711a5a0",
  "command": "find /usr/share/applications -name \"*.desktop\" -exec grep -l \"postgres\\|postgresql\\|psql\\|database\" {} \\; 2>/dev/null",
  "timeout": 10
}
EXIT CODE: 0

STDOUT:


STDERR:

Good, the search pattern is correct - no postgres-related .desktop files exist. The extraction script is working correctly now. Let me submit the result again:

OK: sandbox 'linux-b711a5a0' deleted.

Excellent! I've successfully completed the installation and launch script creation for PostgreSQL on Linux. Here's a summary of what was accomplished:

Summary

Application: PostgreSQL 14.22
OS: Linux (Ubuntu 22.04)
Status: ✅ Complete

Install Script

The install script uses Ubuntu's apt package manager to: - Update the package list - Install PostgreSQL and PostgreSQL contrib packages - Verify the installation with psql --version

Launch Script

The launch script: - Starts the PostgreSQL server as the postgres user - Uses pg_ctl to manage the server process - Verifies the server is accepting connections via pg_isready - Displays connection information and version details

Metadata Extraction

The metadata extraction script: - Dynamically searches /usr/share/applications for PostgreSQL desktop files - Extracts the display name from package metadata (since no .desktop file exists) - Finds SQL-related icons from standard icon directories - Extracts version information from psql --version

Results

Binary Path: /usr/bin/psql
Version: 14.22
Display Name: PostgreSQL (extracted from package metadata)
Icons Found: 2 SQL-related icons
Screenshot: Shows active PostgreSQL prompt with successful connection confirmation

The application is now ready for use with provided install and launch scripts that are fully functional and tested.
