Hello all,
One more interesting observation made by me.
I have ran the below query(s) on production:
SELECT
relname,
age(relfrozenxid) as xid_age,
pg_size_pretty(pg_table_size(oid)) as table_size
FROM pg_class
WHERE relkind = 'r' and pg_table_size(oid) > 1073741824
ORDER BY age(relfrozenxid) DESC ;
relname |
xid_age | table_size

You seem to be rather far from the freeze_max_age. Unless you're consuming txids at a very high rate, I don't think that's your problem.
