The pgbackrest process needs to connect to the database, which means it
needs a user and database. You need this variable if you do not have the
default database, "postgres". If you have a database named postgres, you
can leave this out. Otherwise, yes, it is necessary.

pgBackRest works on a cluster level, so *all* the databases are backed up.
Indeed, it is not possible to only backup some of the databases. It's the
whole cluster.

Probably best to stick to the official docs; this section in particular is
worth a read:
