Query the connected PostgreSQL database with psql. Use when the user asks about their database, tables, rows, schema, or to run SQL against Postgres.

The connection string is in $POSTGRES_URL: pass it to psql as the first argument. psql is preinstalled
once the sandbox has been rebuilt for this capability (Environment card).
- List tables:
psql "$POSTGRES_URL" -c "\dt" - Describe a table:
psql "$POSTGRES_URL" -c "\d <table>" - Run a query:
psql "$POSTGRES_URL" -c "SELECT * FROM <table> LIMIT 20" - Scriptable output (no headers/formatting, one value):
psql "$POSTGRES_URL" -tAc "SELECT count(*) FROM <table>" - List databases / schemas:
psql "$POSTGRES_URL" -c "\l"/psql "$POSTGRES_URL" -c "\dn"
Notes: this is a read-write connection, the connected role's grants bound what you can do. Wrap risky writes
in BEGIN; … COMMIT; and prefer a WHERE on every UPDATE/DELETE.
