Обсуждение: Backup of users and groups?
Is it enough to just copy pg_group and pg_pwd to backup users and groups and to copy those files back to restore? Will this also work from 7.3.x to 7.4.x? Regards, BTJ
Bjorn, You should do a pg_dump all of your database(s) if you want to restore them on to a 7.4 instance. At a minimum, do a pg_dump -s db for the schema, I believe it will dump the users and groups.

No, pg_dump only dumps what is in a single database. Users and groups
span all databases in a cluster, so they are outside the purview of
pg_dump. You *must* use pg_dumpall to dump user and group info.
There is an option to pg_dumpall to dump only this info, and not invoke
pg_dump on each individual database as it normally would do.

Also this is not a JDBC question and is more appropriate for the -general list. Kris Jurka
My first line should have been pg_dumpall, at any rate, the command tom is referring to is pg_dumpall --globals_only make sure you do this before you upgrade.
