Oh, I should note at this point that I'm *not* whining that "someone"
should volunteer to do this, or that "the postgresql project" should
just "make it happen".
I'm fully aware that Pg is a volunteer project and that even if these
speculations were in a vaguely reasonable direction, that doesn't mean
anyone has the time/skills/knowledge/interest to undertake such major
architectural change. I certainly know I have zero right to ask/expect
anyone to - I'm very, very grateful to all those who already spend time
helping out and enhancing Pg. With particular props to Tom Lane for
patience on the -general list and heroic bug-fixing persistence.
Sorry for the rely-to-self, I just realized my post could've been taken
as a whine about Pg's architecture and some kind of demand that someone
do something about it. That couldn't be further from my intent.
