History
Michael Paquier 1dd88201ad Forbid DROP SCHEMA on temporary namespaces 
This operation was possible for the owner of the schema or a superuser.
Down to 9.4, doing this operation would cause inconsistencies in a
session whose temporary schema was dropped, particularly if trying to
create new temporary objects after the drop.  A more annoying
consequence is a crash of autovacuum on an assertion failure when
logging information about an orphaned temp table dropped.  Note that
because of 246a6c8 (present in v11~), which has made the removal of
orphaned temporary tables more aggressive, the failure could be
triggered more easily, but it is possible to reproduce down to 9.4.
