What does it mean to "stop" anyway? Aren't we all just transactions in the snapshot of the universe without a rollback? Our xmin approaches with each passing day. If only I could PITR to my youth, maybe then I could recover that which was long corrupted. If only I had checksums enabled.
In my experience, it won't stop, it never stops, asking it to stop, indeed throwing yourself on the public's mercy pleading for it to stop will only insure a renewed intensity. Godspeed, Tony.
