Re: Bit Mapping operation

In 7.1 it's there... using the |(or) &(and), etc.. operators.  In 7.0.3
it's not although can be added easily.

example:

test=> select 2 | 1;?column?
----------       3
(1 row)

test=> select 2 & 1;?column?
----------       0
(1 row)

test=> select 3 & 1;?column?
----------       1
(1 row)

test=>
