Hi Thomas!
There's feature freeze approaching again. I see that you are working on moving
SLRUs to buffer pools, but it is not clear to which PG version it will land.
And there is 100% consensus that first patch is useful and helps to prevent big
issues. Maybe let's commit 1'st step without lifting default xact_buffers
limit? Or 1st patch as-is with any simple technique that prevents linear search
in SLRU buffers.
Best regards, Andrey Borodin.
