A Haskell library providing Testcontainers integration for PostgreSQL databases. This library simplifies running PostgreSQL containers for testing purposes, with support for various PostgreSQL versions and authentication methods.
- Multiple PostgreSQL Versions: Support for PostgreSQL versions 9 through 17
- Flexible Authentication: Choose between trust-based authentication or username/password credentials
- Log Forwarding: Optional log forwarding to the console for debugging

putStrLn $ "PostgreSQL is running at " ++ show host ++ ":" ++ show port
-- Your test code here
-- Connect to PostgreSQL using host and port
