pg_dump Reference

Extract PostgreSQL schema information by querying system catalogs using patterns modeled after the pg_dump source. This approach guides you in adapting catalog queries and handling version-specific behavior across PostgreSQL 14-18.

pg_dump queries system catalogs using specialized inspecting queries and deparsing helpers to accurately represent database objects. You can model and adapt these query patterns to build schema extraction logic in your own tooling.

Yes, you can adapt PostgreSQL system catalog queries for Go and pgx. The reference provides guidance on translating pg_dump query patterns into pgx-compatible code for building schema extraction features.

Handle version-specific differences across PostgreSQL 14-18 by implementing version-aware system catalog queries. The reference provides strategies for adapting schema extraction logic to account for catalog changes across each PostgreSQL version.

Debug schema extraction issues in inspector and diff components by consulting the pg_dump source to verify your system catalog queries. This helps identify discrepancies between your query logic and expected object representations.
