I was wondering if anyone happens to know whether there is an Aggregate function available in Postgres that can do an OR on a column of the bit varying type. For example I would like to do something as follows: bitstring *-------- 1110 0100 1111 SELECT bitwise_or(bitstring) FROM table; Resulting in: 1111 Any thoughts?
