Right. > - How to call the UDF on the remote server ? postgres_fdw intentionally refuses to do this, because it has no way to know whether q3c_radial_query() is the same function, or even exists at all, on the remote server. Only WHERE clauses involving built-in functions/operators will be pushed across to the remote server. Barring solutions for that philosophical question, you might be able to do something like putting the function call into a view on the remote side and then creating a foreign table that references the view. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
