In this case just a single byte in which you can store states quite
easily. It supports the C-style bit operations & (and) ,| (or, couldn't
get it defined as a single bar though, because the parser didn't like
it) ,^ (xor),! (not). For some applications it is just easier to check
whether certain bits are set/not set. 

If somebody tells me what needs doing, I could try to get it all into a
more usable format. And I have no clue what SQL3 says about bit-types
(varying bits or something or other?) At the moment it is just a single
byte, and perhaps it needs extension to 2 byte, 4-byte types.
