Thanks everyone. There are a lot of different ways to do it! The man page for pg_dumpall says "pg_dumpall also dumps global objects that are common to all databases. (pg_dump does not save these objects.) This currently includes information about database users and groups, tablespaces, and properties such as access permissions that apply to databases as a whole." Is that something we have to worry about if we just use the "pg_dump rhnschema" method to backup? Spacewalk is the only database I have.

I’m trying to backup my postgress DB using the Spacewalk install documentation at https://github.com/spacewalkproject/spacewalk/wiki/SpacewalkBackup, and it fails with the errors below. If I try it without spacewalk running, it gives an error and creates an empty backup file. If I try it with spacewalk running, it creates a 3.9 GB backup file, but I can’t restore it.
