Hi Amit, While doing some housecleaning in my memory and old pending subjects, I found the following very small subject we discussed many month ago. On Thu, 23 Jul 2020 16:20:28 +0530 Amit Kapila <amit.kapila16@gmail.com> wrote: > On Thu, Jul 23, 2020 at 2:37 PM Jehan-Guillaume de Rorthais > <jgdr@dalibo.com> wrote: > > > > On Tue, 21 Jul 2020 17:34:57 +0200 > > Jehan-Guillaume de Rorthais <jgdr@dalibo.com> wrote: > > > On Mon, 20 Jul 2020 15:29:00 +0530 > > > > > > I'll send a patch proposal for Gather Merge on HEAD tomorrow. > > > > Please, find in attachment the patch to release Gather Merge workers as > > soon as they are exhausted. > > > > Okay, thanks. I'll take care of this after pushing the bug-fix patch. The discussed side patch was referenced here: https://www.postgresql.org/message-id/20200723110749.7aa0e15a%40firost Maybe this small matter was lost in the mist of the discussion? Regards,
