-- Get rid of unnecessary compress and decompress support functions.

-- To be allowed to drop the opclass entry for a support function,
-- we must change the entry's dependency type from 'internal' to 'auto',
-- as though it were a loose member of the opfamily rather than being
-- bound into a particular opclass.  There's no SQL command for that,
-- so fake it with a manual update on pg_depend.
