Hi Shirisha,

Just to let you know, there was a more recent attempt at that in [1]
in Jan 2023 , also with a resurrection attempt there in Nov 2023 by
Tomas. Those patches there seemed to have received plenty of attention
back then and were also based on SyncRepWaitForLSN(), but somehow
maybe we ran out of steam and there was not that big interest back
then.

Maybe you could post a review there (for Tomas's more modern recent
patch), if it is helping your use case even today. That way it could
get some traction again?
