Was reading through this again and got to wondering, is pg_dumpall really
necessary? Do you have multiple databases you want to dump at once? If not a
plain pg_dump against a particular database would work. There is also the
advantage that if you use pg_dump -Fc you can use pg_restore. My use case for
pg_dumpall is pg_dumpall -g to get the global information only from the cluster.
I then use pg_dump for individual databases. You would still want to recreate a
template1 because quite a few tools expect it to be there.
