It looks like the problem is that the new range check + /* This range check shouldn't fail, but let's be paranoid */ + return (new_prefetch_pages > 0.0 && new_prefetch_pages < (double) INT_MAX); should be testing for >= 0.0 not > 0.0. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
