One of the issues we had during testing with original patch was db stop not
working properly. I think you coded something to do a stop checkpoint in
immediately but if a checkpoint is already in progress at that time, it
would take its own time to complete.
Does this patch resolve that issue? Also, is it based on pg82stable or HEAD?
