Gosh, I stand corrected. According to http://msdn.microsoft.com/en-us/library/336xbhcz.aspx -- "The result is undefined if the right operand of a shift expression is negative or if the right operand is greater than or equal to the number of bits in the (promoted) left operand. No shift operation is performed if the right operand is zero (0)." -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
