Description

As the pg_autoscaler will be automatically turned on with the 14.2.4 release and future releases I would like to enhance the functionality a bit.

We agreed on that the pg_num should always be a power of two and already updated the docs, so it would be the next step to also implement such check into the autoscaler so a user would directly be warned if they configured something else.

Note: contrary to what the bug description says, pg_autoscaler will (apparently) not be automatically turned on with the 14.2.4 release or any future nautilus release.
