Problem:

Permify doesn't clearly indicate when an incompatible PostgreSQL version is used.

Reproduction:

1. Run Permify.
2. Permify checks PostgreSQL version with Goose.
3. If version is below 13.8, no clear error is shown.

Expected:

If PostgreSQL is below 13.8, Permify should display an error message and not run.

Current Issue:

Lack of clear error for PostgreSQL versions under 13.8.

Solution:

Add a version check at startup. Display an error and stop Permify if the version is too low.
