- add matrix_postgres_backup_databases to be build on top of matrix_postgres_additional_databases
- POSTGRES_DB is now directly set from matrix_postgres_backup_databases while building the templates/env-postgres-backup.j2

- adjusted env-postgres-backup.j2 to use the new role specific variables

This will make data migration easier.

Allow psql args to be given to matrix-postgres-cli

This passes any arguments given to 'matrix-postgres-cli' to the 'psql' command.

Examples:
  $ # start an interactive shell connected to a given db
  $ sudo matrix-postgres-cli -d synapse
  $ # run a query, non-interactively
  $ sudo matrix-postgres-cli -d synapse -c 'SELECT group_id FROM groups;'

If they do, our next playbook runs would simply revert it
and report "changed" for that task.

There's no benefit to letting the bridge spew a new config file.

This does not apply to the mautrix whatsapp bridge, because that one
is written in Go (not Python) and takes different flags. There's no
equivalent flag there.
