dimitr	11495a55fb	Refactored the whole RSB stuff into classes. They're inside the /recsrc sub-directory now. ... Fixed the layering for WITH LOCK and (partially) ANY/ALL predicates. Cleaned up the outdated code that never worked (mapping DISTINCT to an index, some VMS remainings). Wiped out a lot of the pre-ODS11 optimizer logic. Some minor adjustments there. Re-implemented the full outer join from scratch. This resolves CORE-2678 (full outer join cannot use available indices). Resolved CORE-2796: DB_KEY is always zero for external tables. Implemented the core part of the scrollable PSQL cursors. Implementation is still incomplete, but ready for testing. Some other changes I don't recall at the moment ;-) WARNING! The engine may be unstable. Please email me about any issues found.	2009-12-09 18:45:44 +00:00
