That's how I back them up as well. You are correct that all you need to do
is restore the globals.sql, then each "pgdump" file individually. Just
ignore the warning when it tries to restore your initial postgres
superuser, since it was created by the initdb already.
You probably don't need the "postgres" db at all, since it is just there to
allow the client to connect to something on initial install. Normally you
don't use it in production.
