Hi Hackers,
Can we resurrect the patch proposed by Junji TERAMOTO?
It removes unnecessary items before btree pages split.

There was a problem in the patch when we restarted scans from deleted tuples.
But now we scan pages at-a-time, so the problem is resolved, isn't it?

I think this feature is independent from the SITC project and useful for
heavily-updated indexes. If it is worthwhile, I'll revise the patch to
catch up on HEAD.
Regards,
