# PostgreSQL Sessions

## Overview

**PostgreSQL Sessions** provide production-grade session management backed by PostgreSQL database. Ideal for multi-server deployments, high concurrency applications, and enterprise environments requiring ACID guarantees and advanced database features.

## Key Features

- **Production-Ready**: Battle-tested RDBMS with ACID guarantees
- **High Concurrency**: Handle thousands of simultaneous connections
- **Advanced Queries**: Full SQL capabilities for complex analytics
- **Scalability**: Vertical and horizontal scaling options
- **Replication**: Built-in primary-replica replication
- **Backups**: Point-in-time recovery, pg_dump, continuous archiving
- **Security**: Row-level security, encryption, role-based access

## When to Use

✅ **Use PostgreSQL Sessions when:**

- Deploying production web applications
- Need high concurrency (100+ simultaneous users)
- Require advanced analytics and reporting
- Need multi-server deployment with shared state
- Compliance requires ACID transactions
- Want production-grade backup/recovery

❌ **Use SQLite instead when:**

- Building local/desktop applications
- Single-user or low concurrency
- Want zero configuration
- Don't need distributed deployment
