That shouldn't happen :-(. I am guessing the cause is a corrupt
entry in pg_depend. Class 2 is OCLASS_TYPE, so apparently some
type got dropped but its pg_depend entry wasn't cleaned out, so
DROP SCHEMA thinks there's still a dependent object.
I would try to pg_dump the database, and if you can do that and
reload successfully then discard the original. If you've found
one bit of catalog corruption there's likely more.

I second that recommendation. However, there's also pg_catcheck which
could help diagnose and fix things, in case a dump/restore of the whole
database is impractical. If you operate it wrong enough, you can
corrupt your whole database though.
