Marc G. Fournier	59f29714aa	Fixes: This patch forces postgres95 to assume any floating-point value is a float8. It removes the requirement that you cast all floating-point constants to float8. We can remove alot of casts in the regression test after we are sure this works. If I have missed anything, would someone let me know. I have tested inserts of floating-point values into float8 fields, and it worked well. Casting the number to float4 showed the same precision loss as previous uncast values showed.

Marc G. Fournier	20288400f3	Fixes: I have written some patches which add support for NULLs to Postgres95. In fact support for NULLs was already present in postgres, but it had been disabled because not completely debugged, I believe. My patches simply add some checks here and there. To enable the new code you must add -DNULL_PATCH to CFLAGS in Makefile.global. After recompiling you can do things like: insert into a (x, y) values (1, NULL); update a set x = NULL where x = 0; You can't still use a "where x=NULL" clause, you must use ISNULL instead. This could probably be an easy fix to do. Submitted by: Massimo Dal Zotto <dz@cs.unitn.it>	30 years ago
