Hi Fabrízio,
I test your v4 patch, and send your review comments.

We can set negative number at min_standby_apply_delay. I think that this
feature
is for world wide replication situation. For example, master server is in
Japan and slave server is in San Francisco. Japan time fowards than San
Francisco time
. And if we want to delay in this situation, it can need negative number in
min_standby_apply_delay. So I propose that time delay conditional branch
change under following.

What do you think? It might also be working collectry.
what using interval instead absolute time?
This is because local time is recorded in XLOG. And it has big cost for
calculating global time.
