These parameters collectively determine when very old transaction ids are replaced with the special FrozenXID transaction id, which is older than any other transaction id. Old transaction ids must be periodically replaced like this to prevent transaction id wraparound. The only disadvantage of increasing autovacuum_freeze_max_age is increased disk usage, but a value of 2 billion should only require 500MB, which is pretty trivial. Since changing autovacuum_freeze_max_age requires a restart, we will still have to issue a manual VACUUM, with vacuum_freeze_min_age and vacuum_freeze_table_age temporarily set to lower values.
