I've gotten a wide variety of feedback on the proposed patch. The comments range from rough approval through various discussion about alternative solutions. At this point I am unsure if this patch is rejected or if it would be accepted once I had the updated man page changes that were discussed last week.
I have attached an updated patch which does incorporate man page changes, in case that is the blocker. However, if this patch is simply rejected, I'd appreciate it if I could get a definitive statement to that effect.
Thanks,
Jerry

Hello All,Attached is a patch to provide an option to disable WAL recycling. We have found that this can help performance by eliminating read-modify-write behavior on old WAL files that are no longer resident in the filesystem cache. The is a lot more detail on the background of the motivation for this in the following thread.A similar change has been tested against our 9.6 branch that we're currently running, but the attached patch is against master.Thanks,Jerry
