I want to recreate users with their passwords from one database
cluster on another database cluster.  What would be the best way for
me to do this?

Thanks,
Carol

from the "old" server run this (where <new_db_cluster> is the new server):


pg_dumpall -g | psql -h <new_db_cluster>

See pg_dumpall with -g option.

Isn't it generally better to use the newer binaries from the target
server especially with psql?
I remember getting quite a few errors when restoring a pg_dumpall from
an 8.1 server, because the create user syntax in the dump file was obsolete.
You might need some more options for piping (-U etc.):

Generally this is true.

But we're not really doing a pg_dumpall of everything, just he global
objects.  Not sure if there's any issues with a later version versus a
newer version there.  Probably best to use the newer pg_dumpall /
pg_dump than the older one though.
