This doesn't seem particularly surprising: you are going to have to
enter the password once for pg_dumpall, and once for each of its
per-database invocations of pg_dump.

Most people try to set things up so that pg_dump(all) can be executed
without any manual password entry. You might be able to use another
authorization method for local connections; failing that, set up a
~/.pgpass file for the database superuser.
