Marc G. Fournier	07a65b2255	Commit of a *MAJOR* patch from Dan McGuirk <djm@indirect.com> ... Changes: * Unique index capability works using the syntax 'create unique index'. * Duplicate OID's in the system tables are removed. I put little scripts called 'duplicate_oids' and 'find_oid' in include/catalog that help to find and remove duplicate OID's. I also moved 'unused_oids' from backend/catalog to include/catalog, since it has to be in the same directory as the include files in order to work. * The backend tries converting the name of a function or aggregate to all lowercase if the original name given doesn't work (mostly for compatibility with ODBC). * You can 'SELECT NULL' to your heart's content. * I put my _bt_updateitem fix in instead, which uses _bt_insertonpg so that even if the new key is so big that the page has to be split, everything still works. * All literal references to system catalog OID's have been replaced with references to define'd constants from the catalog header files. * I added a couple of node copy functions. I think this was a preliminary attempt to get rules to work.	30 years ago

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
