My impression is that Service-startup is rather nondeterministic in aspects
of timing.

So I would suggest to integrate that sleepy workaround within pg_autovacuum
service. Just let it sleep for 'some time' ... maybe even configurable ...
before it connects. (recommended default: 180 seconds; NOT microseconds and
NOT milliseconds :))

That will not harm anything: on system-startup there is running a lot of
rubbish anyway, so it does really not hurt if the first vacuum-run is 3
minutes later (on a usual system starting up it will take 3 minutes anyway
before scheduling time-slices for vacuum is really sensible)

And really intensly productive servers should not boot anyway. So: nobody
gets hurt, and pg_usleep is very well tested.
