The GUC is not stored in a catalog, but.. oh... it is multiplied by 1000. So if it is larger than (INT_MAX / 1000), it overflows... If we officially accept that (I don't think great) behavior (even only for impractical values), I don't object further. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
