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

We can set negative number at min_standby_apply_delay. I think that this
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
. 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?
