Marc G. Fournier	e4949f9fe5	From: Dan McGuirk <mcguirk@indirect.com> Subject: [HACKERS] better access control error messages This patch replaces the 'no such class or insufficient privilege' with distinct error messages that tell you whether the table really doesn't exist or whether access was denied.	29 years ago

Bruce Momjian	63df35e249	This patch changes quite a few instances of references of Oid's as ints and longs. Touches on quite a few function args as well. Most other files look ok as far as Oids go...still checking though... Since Oids are type'd as unsigned ints, they should prolly be used with the %ud format string in elog and sprintf messages. Not sure what kind of strangeness that could produce. Darren King	29 years ago

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
