FREEZE MIN AGE \ PostgreSQL
Specifies the cutoff age (in transactions) that VACUUM should use to decide whether to replace
transaction IDs with FrozenXID while scanning a table. The default is 50 million transactions.
Although users can set this value anywhere from zero to one billion, VACUUM will silently limit
the effective value to half the value of autovacuum_freeze_max_age, so that there is not an
unreasonably short time between forced autovacuums.
