Ah, well, there's the issue. It could be expected that no tuple
freezing would happen before autovacuum_freeze_max_age. I'd take a zero
off that value I think --- you're not leaving yourself a lot of daylight
between freeze_max_age and wraparound. You could get away with that
setting in a smaller database that didn't take so long to vacuum, but
in a bigger one you want to freeze a bit more aggressively IMHO.
