Hi,
can the VACUUM FREEZE be skipped if
a) txid_current < vacuum_freeze_min_age or if
b) txid_current < vacuum_freeze_table_age or if
c) txid_current < autovacuum_freeze_max_age and no manual VACUUM has
been done?
Or is the operation perhaps only necessary for tables matching
select n.nspname, c.relname, c.relfrozenxid
from pg_class c join pg_namespace n on c.relnamespace=n.oid
where c.relfrozenxid::text::int>=(select setting::int
from pg_settings
where name='vacuum_freeze_min_age')
or similar?
Thanks,
Torsten
