postgresql
Query and inspect PostgreSQL schemas, tables, types, and data in the local development database. Use this skill whenever the user asks about the database schema, wants to inspect a table or type, needs to run a query, or asks anything involving PostgreSQL, psql, or the dev database. Trigger on phrases like "what columns does X have", "check the schema", "look at the type", "query the db", "what does the X table look like", or any time understanding the data model would help answer the question.
