Postgresql 11.2: Cannot connect

Without looking into too much details yet, it appears to me that the package is found and configured to run on the next-available port, 5433: https://travis-ci.org/keithpitty/kpdotcom/builds/507439479#L231. I would imagine that your psql by default will connect to port 5432, but nothing is listening on that port.
