+1. I was just at a client today that had run into this problem.

Actually, I'm in favor of refusing to start if autovac is on but the
proper stats settings aren't. I'd rather that then people ending up
bloated databases and crappy performance.

I agree, but I figured that this was a start, at least.

The problem with refusing to start is that autovacuum is sighup, so you
might modify postgresql.conf and do a server restart, and then the
server doesn't start.  Are people OK with that?

I did apply the postgresql.conf comment addition.

Hrm... how about if the options are incompatible on HUP we refuse to pick up any new settings and complain loudly?

Perhaps it would be easier to just override stats_row_level if autovac is on. Doesn't necessarily meet the least surprise test, but it does protect newbies which I feel is more important in this case.
