You can list database schemas and tables, generate basic `CREATE TABLE` DDL, preview table data with customizable limits, and execute ad-hoc SQL queries, with automatic `LIMIT` application for safety.

Question 5

How do I configure my Postgres connection?

Accepted Answer

The Postgres connection is configured using standard environment variables such as `PGUSER`, `PGPASSWORD`, `PGHOST`, `PGDATABASE`, and `PGPORT`, which the server reads upon startup.
