I wonder whether it would be better to have it still be a read-write parameter, but with min/max values equal to zero. All the other cases where we have read-only parameters, they're *always* read-only. It seems a bit odd that this one is platform-specific not only as to the allowed range but whether it can be assigned at all. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
