Revert "Reduce checkpoints and WAL traffic on low activity database server"
This reverts commit 18fb9d8d21a28caddb72c7ffbdd7b96d52ff9724. Per discussion, it does not seem like a good idea to allow committed changes to go un-checkpointed indefinitely, as could happen in a low-traffic server; that makes us entirely reliant on the WAL stream with no redundancy that might aid data recovery in case of disk failure. This re-introduces the original problem of hot-standby setups generating a small continuing stream of WAL traffic even when idle, but there are other ways to address that without compromising crash recovery, so we'll revisit that issue in a future release cycle.
