Convert CONCATENATE and aggregate functions to it.
Fix some bugs:
- select sum(n) over (order by n2), sum(n) over (), n, n2 from x1;
- select (select 1 from x1 b where list(1, a.n) = 1) from x1 a;
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Cleaned up the outdated code that never worked (mapping DISTINCT to an index, some VMS remainings).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.
2) Make exceptions in metadata charset and convert them to the client charset - this should fix CORE-2431
3) Support for "internal" (engine) DSQL statements and use in COMMENT ON
CORE-462 New option in addition to -V switch to specify a custom verbose interval
CORE-2540 Utilities need a more coherent way to show help and version
CORE-2541 Too many hardcoded messages in nbackup
CORE-2542 qli and nbackup accept arbitrary input after the first letter of an option
CORE-2543 nbackup may hide the real cause of failure
CORE-2545 Lack of several validations in gbak
CORE-2547 Utilities need to honor their minimum number of characters to recognize an option
CORE-2565 Many hardcoded messages in Trace Manager
Moving functions that don't depend on preprocessing to iutils.cpp in isql is the only alien change here.
