Hello Andres,
I would rather separate them, unless this is a blocker.
I think it is a blocker.
Hmmm. This is an argument...
This version seems already quite effective and very light. ISTM that
adding a sort phase would mean reworking significantly how the
checkpointer processes pages.
Meh. The patch for that wasn't that big.
Hmmm. I think it should be implemented as Tom suggested, that is per
chunks of shared buffers, in order to avoid allocating a "large" memory.
The problem with doing this separately is that without the sorting this
will be slower for throughput in a good number of cases. So we'll have
yet another GUC that's very hard to tune.
ISTM that the two aspects are orthogonal, which would suggests two gucs
anyway.
