Crash on startup when not using postgres

Bug report

Describe the bug

When strapi is not using postgres, the server crashes on startup

Steps to reproduce the behavior

1. Start a strapi instance without using postgres
2. The info message is logged, but the server crashes

Expected behavior

The plugin should be disabled and the server should start without it

Additional context

I noticed you already have a check in there for plugin disabled, I believe it just needs to be added to a few more places.
