Nah, false alarm, it's working as expected for me. And I see the age of
databases being correctly decreased to the freeze min age (plus however
many transactions it took to do the vacuuming work). So I'm still at a
loss on why is it failing to advance the datfrozenxid of your database.
Please let me have a look at this query result while connected to that
database:
select relname, relfrozenxid from pg_class where relkind in ('r', 't');
You can change the relname to oid if showing the table names is
problematic for you.
