Is your proposal related to a problem?

During startup of the lemmy containers, if postgres isn't ready to accept connections yet lemmy will log the failed attempt and include username/password in that log.

Log files may have less stringent permissions, whilst the postgres password itself is part of a docker secret.

Example:
Error connecting to postgres://lemmy:PASSWORDHERE@lemmy-postgres:5432/lemmy: connection to server at "lemmy-postgres" (172.21.2.3), port 5432 failed: FATAL: the database system is not yet accepting connections

Describe the solution you'd like.

Replace the password with a single "x", or some other suitable subtitute.
If required, an additional environment label could be used to re-enable credentials in logs, although I wouldn't recommend it.

Describe alternatives you've considered.
