Password leaks as plaintext in log

[egasimus]

Issue Summary

If connecting to the database fails, the database password is printed in plaintext in the system log.

Steps to Reproduce

Try to connect with invalid settings, and the backend daemon will dutifully report:

thread 'main' panicked at 'Error connecting to postgres://username:password@host:port/db

Technical details

Maybe the panic handler should check for sensitive data?
