dblink now has its own validator function dblink_fdw_validator(), which is better than the core function postgresql_fdw_validator() because it gets the list of legal options from libpq instead of having a hard-wired list. Make the dblink extension module provide a standard foreign data wrapper dblink_fdw that encapsulates use of this validator, and recommend use of that wrapper instead of making up wrappers on the fly. Unfortunately, because ad-hoc wrappers *were* recommended practice previously, it's not clear when we can get rid of postgresql_fdw_validator without causing upgrade problems. But this is a step in the right direction. Shigeru Hanada, reviewed by KaiGai Kohei |
