Comment:

 Yes I am convinced

 Thanks a lot :-)

 I missed the fix before the examples.

 A side note.

 From the expression we get a logical true or false, then that is cast to
 integer because PostgreSQL otherwise won't let us cast it to double
 precision. So we can put it in a 1 bit pixel ...

 I guess this is a result of the flexibility Pierre was talking about, but
 it seems like a long way for a boolean.

 Thanks again
 Nicklas
