Why is that needed? It's already a no-op AFAIR. It also is
incompatible with the existing behavior, in which nonexistent schemas
(think "$user") are dropped silently rather than noisily. Your patch
also breaks the previous careful tweak to allow ALTER DATABASE SET
to succeed when mentioning a schema not present in the current database.

This requires considerable discussion. Should \df only list functions
you are allowed to call? \dt only tables you are allowed to read?
\h only commands you are allowed to execute?
I'm not that thrilled with patches that propose basic changes in
behavior and have not been justified by any preceding discussion
on pghackers...
