django.db.utils.OperationalError: could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
Port 5432 is PostgreSQL. MAAS is racing with PostgreSQL during init. We could make MAAS retry, we could ensure that maas-regiond loads after postgresql (i.e. update maas-regiond's Upstart script), or we could do both. The quickest is probably the init script change.
