Probably because it seemed like a round number, which 9 wasn't ... keep in mind that this data structure is nominally intended to support other lock semantics besides what LockConflicts[] defines. (BTW, it's a conceptual error to imagine that the numerical values of the lock mode codes define a strict "strength" ordering, which is another reason I don't care for your patch.) 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
