Backup of users and groups?

From

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?

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.

pg_dump only operates on one database, to dump cluster global entities
like users and groups pg_dumpall should be used.

Also this is not a JDBC question and is more appropriate for the -general
list.

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.
