The previous coding attempted to activate all the GUC settings specified in SET clauses, so that the function validator could operate in the GUC environment expected by the function body. However, this is problematic when restoring a dump, since the SET clauses might refer to database objects that don't exist yet. We already have the parameter check_function_bodies that's meant to prevent forward references in function definitions from breaking dumps, so let's change CREATE FUNCTION to not install the SET values if check_function_bodies is off. Authors of function validators were already advised not to make any "context sensitive" checks when check_function_bodies is off, if indeed they're checking anything at all in that mode. But extend the documentation to point out the GUC issue in particular. (Note that we still check the SET clauses to some extent; the behavior with !check_function_bodies is now approximately equivalent to what ALTER DATABASE/ROLE have been doing for awhile with context-dependent GUCs.) This problem can be demonstrated in all active branches, so back-patch all the way. |
