When to choose this server

This is the older PostgreSQL reference server, now documented in the servers-archived repository. It offers schema inspection and SQL queries described as read-only in the upstream README.

Setup and limitations

For a new deployment, compare maintained database integrations first. If evaluating this reference, use a disposable database and a database-enforced read-only role; do not rely only on the tool description. Its former servers/main/src/postgres source link is no longer the current location.

These notes check the linked documentation, not a live authenticated connection. Suggested checks are steps for you to run.
