The table-skipping logic in autovacuum would fail to consider that multiple workers could be processing the same shared catalog in different databases. This normally wouldn't be a problem: firstly because autovacuum workers not for wraparound would simply ignore tables in which they cannot acquire lock, and secondly because most of the time these tables are small enough that even if multiple for-wraparound workers are stuck in the same catalog, they would be over pretty quickly. But in cases where the catalogs are severely bloated it could become a problem. Backpatch all the way back, because the problem has been there since the beginning.
