Hi, In HEAD, when autovacuum is disabled, autovacuum process is not launched forcibly to prevent XID wraparound even if we go through autovacuum_freeze_max_age. This seems to be because ShmemVariableCache->xidVacLimit is not initialized (i.e., SetTransactionIdLimit() is not called) until VACUUM is performed.
OTOH, in older version, ShmemVariableCache->xidVacLimit is always initialized when backend updates the flat database file, and then autovacuum process seems to be launched forcibly as expected. Is this bug? I guess that it derives from the changes around flag file done a while ago.
