I'm sorry for my late review...
I feel potential of your patch in PG replication function, and it might be
something useful for all people. I check your patch and have some comment for
improvement. I haven't executed detail of unexpected sutuation yet. But I think
that under following problem2 is important functionality problem. So I ask you to
solve the problem in first.
* Regress test
Your patch does not code recovery.conf.sample about recovery_time_delay.
Please add it.
When I set time-delayed standby and start standby server, I cannot access stanby
server by psql. It is because PG is in first starting recovery which cannot
access by psql. I think that time-delayed standby is only delayed recovery
position, it must not affect other functionality.
I didn't test recoevery in master server with recovery_time_delay. If you have
detail test result of these cases, please send me.
My first easy review of your patch is that all.
