Tom Lane b154d8a6d0 Add pg_basetype() function to extract a domain's base type. ... This SQL-callable function behaves much like our internal utility function getBaseType(), except it returns NULL rather than failing for an invalid type OID. (That behavior is modeled on our experience with other catalog-inquiry functions such as the ACL checking functions.) The key advantage over doing a join to pg_type is that it will loop as needed to find the bottom base type of a nest of domains.
