Description
This PR introduces a new PostgreSQL-specific guide to help users containerize PostgreSQL databases using Docker. The guide is structured into four progressive modules:
Immediate Setup & Data Persistence - Covers running PostgreSQL containers with proper data persistence using named volumes, bind mounts, and Docker Compose configurations.
Advanced Configuration and Initialization - Explains initialization scripts (/docker-entrypoint-initdb.d/), performance tuning parameters (memory settings, connection limits, I/O
configuration), and timezone/locale settings.
Networking and Connectivity - Details how to configure networking for containerized PostgreSQL deployments.
Companions for PostgreSQL - Introduces ecosystem tools including pgAdmin 4 for visual management, PgBouncer and Pgpool-II for connection pooling, and pgbench for performance testing.
Examples include tabs showing both Docker Hardened Images (DHI) and Docker Official Images (DOI) variants where applicable.
The guide is prepared by @igor-alexandrov, @edithturn, and @Expeto.
