# PG Idempotent

Transform PostgreSQL migrations into idempotent versions that can be safely run multiple times without errors. **Includes native Supabase integration!**

## What It Does

- **Makes SQL migrations safe to re-run** - No more broken deployments from partial migration failures
- **Native Supabase support** - Automatically detects and processes Supabase migration files
- **Preserves original functionality** - Adds safety checks without changing behavior
- **Works with any PostgreSQL setup** - Supabase, raw PostgreSQL, Docker, etc.

## Quick Start

### Installation

```sh
# Basic installation (core functionality)
pip install pg-idempotent

# With all optional features (test generation, validation, etc.)
pip install pg-idempotent[all]
```

### For Supabase Projects

```sh
# Check your migration files
pg-idempotent supabase check

# Fix them to be idempotent
pg-idempotent supabase fix

# Now safely deploy
supabase db push
```

### For General PostgreSQL

```sh
# Transform a single file
pg-idempotent transform migration.sql

# Process multiple files
pg-idempotent batch migrations/ --recursive
```

## CLI Commands

```sh
pg-idempotent --help
```

<summary>Prerequisites</summary>

1. [Generate an SSH key](https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#generating-a-new-ssh-key) and [add the SSH key to your GitHub account](https://docs.github.com/en/authentication/connecting-to-github-with-ssh/adding-a-new-ssh-key-to-your-github-account).
1. Configure SSH to automatically load your SSH keys:

    ```sh
    cat << EOF >> ~/.ssh/config
    
    Host *
      AddKeysToAgent yes
      IgnoreUnknown UseKeychain
      UseKeychain yes
      ForwardAgent yes
    EOF
    ```

1. [Install Docker Desktop](https://www.docker.com/get-started).
1. [Install VS Code](https://code.visualstudio.com/) and [VS Code's Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers). Alternatively, install [PyCharm](https://www.jetbrains.com/pycharm/download/).
1. _Optional:_ install a [Nerd Font](https://www.nerdfonts.com/font-downloads) such as [FiraCode Nerd Font](https://github.com/ryanoasis/nerd-fonts/tree/master/patched-fonts/FiraCode) and [configure VS Code](https://github.com/tonsky/FiraCode/wiki/VS-Code-Instructions) or [PyCharm](https://github.com/tonsky/FiraCode/wiki/Intellij-products-instructions) to use it.

<summary>Developing</summary>

- This project follows the [Conventional Commits](https://www.conventionalcommits.org/) standard to automate [Semantic Versioning](https://semver.org/) and [Keep A Changelog](https://keepachangelog.com/) with [Commitizen](https://github.com/commitizen-tools/commitizen).
- Run `poe` from within the development environment to print a list of [Poe the Poet](https://github.com/nat-n/poethepoet) tasks available to run on this project.
- Run `uv add {package}` from within the development environment to install a run time dependency and add it to `pyproject.toml` and `uv.lock`. Add `--dev` to install a development dependency.
- Run `uv sync --upgrade` from within the development environment to upgrade all dependencies to the latest versions allowed by `pyproject.toml`. Add `--only-dev` to upgrade the development dependencies only.
- Run `cz bump` to bump the package's version, update the `CHANGELOG.md`, and create a git tag. Then push the changes and the git tag with `git push origin main --tags`.
