Thanks. Yeah, I was basically looking for the role/user only version of pg_dumpall -g, where I'd then handle specific DB restore on its own. Your right thought, I can copy out what I care about from the output.
I am doing a pg_restore of a database, which is nothing difficult, but I also am creating a new server first, and rather than painstakingly making sure I create all users and roles etc prior to pg_restore (so we can have the same perms), is there some obvious way of doing this I'm unawares of?
Running "pg_dumpall -g > source_roles.sql" and then scanning it for the relevant entries doesn't seem too onerous. It's a lot easier than the conceptually similar -- but much trickier -- process you need to go through when migrating SQL Server databases.
