No, those are expected. I'm having a hard time reproducing the behavior
right now, but IIRC the delays were in the vacuum and/or sanity_check
tests. It's not unlikely that the foreground VACUUM was blocking on a
lock while autovac did the same work, except that that doesn't explain
the length of the pause, nor the lack of disk activity.
But I can't make it happen right now, so nevermind until I figure out
how to reproduce it ...
