PostgreSQL pg_dump Reference

About

The pg-dump-reference skill acts as a specialized knowledge layer for developers working with PostgreSQL internals. It leverages pg_dump as the authoritative source for querying system catalogs, understanding internal object representations, and handling complex dependency relationships. Whether you are building database migration tools, ORMs, or schema inspectors, this skill helps you implement robust logic by following the same patterns used by the official PostgreSQL dump utility, ensuring compatibility across versions 14 through 17.

Key Features

• Mapping of database objects to specific pg_dump source code functions
• Guidance on using internal functions like pg_get_expr and pg_get_constraintdef
• Best practices for DDL formatting and object dependency sorting

Use Cases

• Implementing custom database schema introspection and discovery tools
• Developing declarative schema management systems with accurate DDL generation
• Debugging complex system catalog queries in Go, Python, or Node.js database drivers
