Re: Do we reduce autovacuum_naptime max values

I have seen similar issues with other flags. Specifically, without
careful consultation of the documentation, it is easy to misconfigure
these parameters due to the varying default unit semantics.

This made me think about the vacuum failsafe mechanism. Although the
failsafe successfully overrides certain cost and delay restrictions to
speed up anti-wraparound vacuuming once a vacuum process kicks in, an
accidentally high naptime creates a scheduling bottleneck. It prevents
the launcher from initiating the autovacuum processes in the first
place.
