Hi Stephen,

The new approach was suggested after completion of GSoC. So, I didn't get
enough time to implement this approach. Also, I was constantly updating my
patches for gist and gin index based on reviews.

Here, I am attaching the rebased version of the patch (which is based on an
old approch:
acquiring a predicate lock on primary page of a bucket)

Kind Regards,
