Postgres Best Practices

Guidelines and best practices for working with Postgres, covering schema design, indexing, query optimization, and common pitfalls.

Supported Versions

This skill covers PostgreSQL 14 through 18. Version-specific features are tagged (e.g., [PG15+], [PG18+]); environment-dependent examples identify required privileges, extensions, or multi-node setup.

PostgreSQL provides 5 years of support per major version. Always run the latest minor release.
