Thanks!

I remain curious, though: in the event that a RAM-disk-based
architecture remains in place, do all traditional disk-based
considerations go out the window? For instance, does trying to
cluster same-table statements together in a transaction in an effort
to reduce disk activity make any difference?

And is the overall strategy of attempting to keep distance between
checkpoints somewhat high (especially since the need for
checkpointing overall is reduced) still a good basis?
