Re: Batching in executor - Mailing list pgsql-hackers

Hi Tomas,

Thanks a lot for your comments and benchmarking.

I plan to reply to your detailed comments and benchmark results, but I
just realized I had forgotten to attach patch 0008 (oops!) in my last
email. That patch adds batched qual evaluation.

I also noticed that the batched path was unnecessarily doing early
“batch-materialization” in cases like SELECT count(*) FROM bar. I’ve
fixed that as well. It was originally designed to avoid such
materialization, but I must have broken it while refactoring.
