However, my comment above was too optimistic, because in an insert-only
scenario autovac would in fact not trigger VACUUM at all, only ANALYZE.
So it seems like we do indeed want to rejigger autovac's rules a bit
to account for the possibility of wanting to apply vacuum to get
visibility bits set.
I'm sure I'm missing something, but I thought the point of this was to
lessen the impact of VACUUM and now you are suggesting that we have to
add vacuums to tables that have never needed one before.
