1997-01-22Cast constants to the type of the other binary operand.Bruce Momjian
Invalidate vacuum relation cache to use new row counts from vacuum.
1996-12-26I have this annoying habit (among others) of puttingBruce Momjian
%ud in a printf format strings instead of just %u. There were three occurances of this in catalog_utils.c, two in parser.c and one in rewriteSupport.c in the oid patch that I submitted and was applied. They won't crash anything, but the error messages will have a 'd' after the Oid. Annoying, but none are db-threatening. Sorry about that folks...I'll be more careful in the future... Darren King

1996-11-30This patch changes quite a few instances of references of Oid'sBruce Momjian
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

Now You can do queries like select sum(some_func(x)) from ... select min(table1.x + table2.y) from table1, table2 where ... and so on. Vadim

1996-11-13Commit of a *MAJOR* patch from Dan McGuirk <[email protected]>Marc G. Fournier
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.

1996-07-19Fixes:Marc G. Fournier
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 <[email protected]>
