Etsuro Fujita 8b6da83d16 postgres_fdw: Account for triggers in non-direct remote UPDATE planning. ... Previously, in postgresPlanForeignModify, we planned an UPDATE operation on a foreign table so that we transmit only columns that were explicitly targets of the UPDATE, so as to avoid unnecessary data transmission, but if there were BEFORE ROW UPDATE triggers on the foreign table, those triggers might change values for non-target columns, in which case we would miss sending changed values for those columns. Prevent optimizing away transmitting all columns if there are BEFORE ROW UPDATE triggers on the foreign table. This is an oversight in commit 7cbe57c34 which added triggers on foreign tables, so apply the patch all the way back to 9.4 where that came in.
