Yes, I fixed the problem. If a checkpoint by user SQL or shutdown is waiting during an automatic checkpoint, the running checkpoint will be done without any delays. At the worst case, you have to wait two checkpoints, (a running automatic checkpoint and your explicit request) but nothing more of them. > Also, is it based on pg82stable or HEAD? It's based on HEAD.

Delay factors in checkpoints can be specified by checkpoint_write_percent, checkpoint_nap_percent and checkpoint_sync_percent. They are relative to checkpoint_timeout. Also, checking of archive_timeout during checkpoints and some error handling routines were added. 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?
