Sorry for the delay. I've finally gotten back to this patch, as it's
the simpler option vs the patch in the original thread, even if it may
have a higher performance impact for GIST and SP-GIST IOS scans.
Attached is v02, which is a simple rebase with some language and
wrapping changes in comments, as well as some fixes for assert-enabled
builds.
Kind regards,
