Hi Fabrizio,

looks good to me. I did some testing on 9.2.4, 9.2.5 and HEAD. It
applies and compiles w/o errors or warnings. I set up a master and two
hot standbys replicating from the master, one with 5 minutes delay and
one without delay. After that I created a new database and generated
some test data:

CREATE TABLE test (val INTEGER);
INSERT INTO test (val) (SELECT * FROM generate_series(0, 1000000));

The non-delayed standby nearly instantly had the data replicated, the
delayed standby was replicated after exactly 5 minutes. I did not
notice any problems, errors or warnings.


Thanks for your review Christian...

So, I proposed this patch previously and I still think it's a good
idea, but it got voted down on the grounds that it didn't deal with
clock drift.  I view that as insufficient reason to reject the
feature, but others disagreed.  Unless some of those people have
changed their minds, I don't think this patch has much future here.


I would agree that it is a good idea.
