Re: [PATCH] Auto vacuum should still run when clock is set back

The clock changes are not due to DST, but the UTC system time. There was an NTP server on an offline network that went from 2019 to 2006 due to GPS week number rollover. The date being wrong did cause some problems, but nothing fatal, but several machines filled up their disk to the point of failure because autovacuum was no longer running.

I will attempt to attach the patch again.
