This must be happening when you first try to use the pg_temp_4 schema
inside a particular session. The code will try to remove the existing
schema contents (as indicated by pg_depend), and evidently there is
something inconsistent in that.

What rows do you have in pg_depend that have either objid or refobjid
equal to 463558 or 463559? Also, get the OID of the pg_temp_4 schema
from pg_namespace, and see what rows in pg_depend have refobjid equal
to that.
