pg-aiguide
pg-aiguide is an MCP server and Claude plugin from Timescale that provides AI coding assistants with semantic search over PostgreSQL documentation and curated best-practice skills, producing more accurate, modern, and constraint-rich SQL and schema designs.
Best When
An engineer is using an AI coding assistant to design or modify PostgreSQL schemas and wants production-quality output with proper indexing, constraints, and modern PG features rather than generic boilerplate.
Avoid When
The database is not PostgreSQL, or the team has its own internal schema standards that override general best practices.
Use Cases
- • Generating PostgreSQL schemas with proper constraints, indexes, and PG17-recommended patterns instead of generic SQL
- • Searching version-aware PostgreSQL documentation during schema design or query optimization tasks
- • Getting TimescaleDB and PostGIS documentation and best practices surfaced automatically in AI coding contexts
- • Reducing AI hallucination of outdated or incorrect PostgreSQL patterns through curated skill injection
Not For
- • Non-PostgreSQL databases (MySQL, SQLite, MongoDB, etc.)
- • Developers who don't use AI coding assistants
- • Simple CRUD apps where schema quality is not a priority
