I started reviewing this patch. I did not much like the fact that it
effectively moved rewriteTargetListUD to a different file and renamed it.
That seems like unnecessary code churn, plus it breaks the analogy with
rewriteTargetListIU, plus it will make back-patching harder (since that
code isn't exactly the same in back branches). I see little reason why
we can't leave it where it is and just make it non-static. It's not like
there's no other parts of the rewriter that the planner calls.
I revised the patch along that line, and while at it, refactored
preptlist.c a bit to eliminate repeated heap_opens of the target
relation. I've not really reviewed any other aspects of the patch
yet, but in the meantime, does anyone object to proceeding this way?
regards, tom lane
