6.9Currently,it is at 166846989 and I am not able to vacuum the same as datallowconn is false. Thought of setting it to
trueand perform a vacuum freeze on the same. Before doing that, I wanted to check whether I should be worrying for
somethinghere 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).
