It seems like we should have an upper limit on the GUC variable that's
less than INT_MAX ;-). Would an hour be sane? 10 minutes?
This is independent of the problem at hand, though, which is that we
probably want the launcher to notice postmaster death in less time
than autovacuum_naptime, for reasonable values of same.
Do we need a configurable autovacuum naptime at all? I know I put it in
the original contrib autovacuum because I had no idea what knobs might
be needed. I can't see a good reason to ever have a naptime longer than
the default 60 seconds, but I suppose one might want a smaller naptime
for a very active system?
A PostgreSQL database on my laptop for testing. It should use as little
resources as possible while being idle. That would be a scenario for
naptime greater than 60 seconds, wouldn't it?
