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...
