--
-- As of 9.1, type citext should be marked collatable.  There is no ALTER TYPE
-- command for this, so we have to do it by poking the pg_type entry directly.
-- We have to poke any derived copies in pg_attribute or pg_index as well,
-- as well as those for arrays/domains based directly or indirectly on citext.
-- Notes: 100 is the OID of the "pg_catalog.default" collation --- it seems
-- easier and more reliable to hard-wire that here than to pull it out of
-- pg_collation.  Also, we don't need to make pg_depend entries since the
-- default collation is pinned.
