-- this is a downgrade path that will revert the changes made in citus--9.2-4--9.3-2.sql
--
-- 9.3-2 added citus extension owner as a distributed object, if not already in there.
-- However we can not really know if it was a distributed owner prior to 9.3-2.
-- That's why we leave the record in place.
-- Revert the return type to void
