Thought of setting it to true and perform a vacuum freeze on the same. Before doing that, I wanted to check whether I should be worrying for something here or can I just go ahead with my plan. I would leave well enough alone. Unless you've changed the default values of autovacuum parameters, that behavior is perfectly normal and not worrisome. autovacuum should kick in and do something about it at 200 million xacts (autovacuum_freeze_max_age). regards, tom lane
