Tom Lane 5dde1db4e1 plpgsql's exec_simple_cast_value() mistakenly supposed that it could bypass ... casting effort whenever the input value was NULL. However this prevents application of not-null domain constraints in the cases that use this function, as illustrated in bug #4741. Since this function isn't meant for use in performance-critical paths anyway, this certainly seems like another case of "premature optimization is the root of all evil". Back-patch as far as 8.2; older versions made no effort to enforce domain constraints here anyway.		2009-04-02 01:16:17 +00:00
