Name and Version

bitnami/postgresql:16.6.0

What architecture are you using?

amd64

What steps will reproduce the bug?

Backups fail when using password files with the error "no password supplied".
Overriding with usePasswordFiles=false to use env vars restores functionality.
Cannot find any override or doc to make it fetch the password from the files instead.

Are you using any custom parameters or values?

backup:
  ## @param backup.enabled Enable the logical dump of the database "regularly"
  enabled: true

What is the expected behavior?

Working backups :)

What do you see instead?

pg_dumpall: error: connection to server at "name-of-pgcontainer" (ip of pgcontainer), port 5432 failed: fe_sendauth: no password supplied
