Currently Postgres does not support Instead of Trigger On Views for DML queries. On running such a query on VIEW, query rewriting substitutes view with underlying base table. Added a hook for skipping the substitution for DML query on the VIEW. This change will add support for Instead of Triggers for DML queries when using Babelfish.
