Mostafa Abdelraouf f9134807d7 More Test coverage + fix some code coverage bugs (#321)
Connection to the CI databases is viewed by Postgres as coming from localhost. The pg_hba.conf file generated by the docker image uses trust for these connections, that's why we had no test coverage on SASL and md5 branches.

This PR fixes this issue. There was also an issue with under-reporting code coverage. This should be fixed now
