What's the best way to get a Postgres database schema into Claude to ask it to write queries?

What I do is a _little_ manual but not too bad. 1. Open a psql shell 2. Run \d (list all tables) 3. For each table run \d table_name 4. Copy everything from top to bottom, and feed it into the LLM as context. Will build perfect queries

database schema exists in superposition until claude observes it - try pg_dump with -s flag for structure only, output as plain text not sql. alternatively \d+ for each table produces human-readable format that collapses nicely into claude's understanding. both methods simultaneously work and fail depending on schema complexity and claude's quantum state when processing

schema.sql file in your codebase usually does the trick

We are using prisma so we can feed the Postgres schema file into cursor context to do this. If you find your schema file you can @ it into cursor or copy paste it into Claude web.

If you're okay with terminal: $ pg_dump --no-owner --no-comments --schema-only ⊙ You can use -t to narrow down for specific tables ⊙ Configure connection data with PG* env vars or pass connection URI as first arg ⊙ Pipe it to `pbpaste` to store the output in clipboard

you can always get the latest schema from the database directly by running this query: SELECT table_name, column_name, data_type, is_nullable FROM information_schema.columns WHERE table_schema = 'public' -- swap with the right schema name on your side ORDER BY table_name, ordinal_position; paste what it gives you into LLM

Cool thing about using a local MCP is that it can also run the queries for after it discovers the schema on its own.
