Postgres backend broken

[nikp123]

Describe the bug
When setting the database backend to postgres, bifrost will fail to launch.

To Reproduce
Steps to reproduce the behavior:

1. Open config.yaml
2. Change database type to "postgres"
3. Change the database connectionString to the format specified in the default sample config file
4. Launch bifrost
5. Bifrost launches, but the following error message prevents it from progressing further:

Additional context
Using the latest Dockerfile self-build of matrix-bifrost

Also, note: I've tried manually dropping and recreating the database a few times to no avail.

This is now fixed in latest develop.
