I attach MERGE v14. This includes a fix from Amit Langote for the
problem I described previously, with EvalPlanQual not working correctly.
(I had failed to short-circuit the cross-partition update correctly.)
Now the test case is enabled again, and it passes with the correct
output.
0001 is as before; the only change is that I've added a commit message.
Since this just moves some code around, I intend to get it pushed very
soon.
0002 is the ExecUpdate/ExecDelete split. I cleaned up the struct
definitions a bit more, but it's pretty much as in the previous version.
0003 is the actual MERGE implementation. Many previous review comments
have been handled, and several other things are cleaner than before.
I haven't made any changes for work_mem handling in ModifyTable's
transition tables, though, and haven't attempted to address concurrent
INSERT.
