They're not "supposed to provide the same results".  Per SQL99, the
schemata view is supposed to

         Identify the schemata in a catalog that are owned by a given user.

and the SQL definition in the spec makes it clear that it only shows
schemas owned by CURRENT_USER or a role that CURRENT_USER is a member
of.
