* 1. Vacuum is updated for MVCC.Vadim B. Mikheev1999-03-281-2/+12
| | | | | | | 2. Much faster btree tuples deletion in the case when first on page index tuple is deleted (no movement to the left page(s)). 3. Remember blkno of new root page in BTPageOpaque of left/right siblings when root page is splitted.

* Thank god for searchable mail archives.PostgreSQL Daemon1998-01-151-3/+2
| | | | | | | | | Patch by: wieck@sapserv.debis.de (Jan Wieck) One of the design rules of PostgreSQL is extensibility. And to follow this rule means (at least for me) that there should not only be a builtin PL. Instead I would prefer a defined interface for PL implemetations.

* 1. BTREE_VERSION_1: using bti_itup->t_tid as unique identifier for a givenVadim B. Mikheev1997-04-161-42/+21
| | | | | | | | | | | | index tuple (logical position within A LEVEL). bti_oid & bti_dummy taken off from BTItemData. 2. Fix for multi-column indices (nbtsearch.c): _bt_binsrch() - for searches on internal pages having keysize < number of attrs we point at the last item < the scankey, not at the first item = the scankey; _bt_moveright() - if keysize < number of attrs we compare scankey with _last_ item on current page to decide should we move right or not.
* + NULLs handlingVadim B. Mikheev1997-03-241-8/+112
| | | | | | | | | | | Actually required by multi-column indices support. We still don't use btree for 'A is (not) null', but now btree keep items with NULL attrs using single rule for placing/finding items on pages: NULLs greater NOT_NULLs and NULL = NULL. + Bulkload code (nbtsort.c) support for multi-column indices building and NULLs. + Fix for btendscan()->pfree(scanopaque) from Chris Dunlop.

* Commit of a *MAJOR* patch from Dan McGuirk <djm@indirect.com>Marc G. Fournier1996-11-131-45/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
