Tom Lane d97c9b3662 Apply fixes for problems with dropped columns whose types have also been ... dropped. The simplest fix for INSERT/UPDATE cases turns out to be for preptlist.c to insert NULLs of a known-good type (I used INT4) rather than making them match the deleted column's type. Since the representation of NULL is actually datatype-independent, this should work fine. I also re-reverted the patch to disable the use_physical_tlist optimization in the presence of dropped columns. It still doesn't look worth the trouble to be smarter, if there are no other bugs to fix. Added a regression test to catch future problems in this area.		2003-05-12 00:17:03 +00:00
