Hi! I looked through this thread.
Looks like we are still awaiting a patch which stores more counters
(n_dead_tup, ... etc) into relfilenode stats. So, I assume this should
be moved to the next CF.
I also have a very stupid question:
If we don’t have the relation OID when writing buffers out, can we
just store oid to buffertag mapping somewhere and use it?
I suspect that this is a horrible idea, but what's the exact reason?
Is it that we will break too many abstraction layers for such a minor
matter?
