Yeah. The existing commentary about that is basically justifying 8K as being large enough to avoid performance issues; if somebody can show that that's not true, I wouldn't have any hesitation about kicking it up. (Might be worth malloc'ing it rather than having it as part of the static process image if we do so, but that's a trivial change.) regards, tom lane
