OK,

I'm gonna make it an option. But, as I mentioned before, there are some
weirdnesses with Access.  Here's another weird thing with the way it handles
NULL SQL_BIT columns.

If I have my Postgres bool column, and it contains a NULL, Access automatically
displays it as "0".  Then if I try to update the record, it uses the "0" in the
where clause.  Well guess what, no records are updated because the "0" doesn't
match the NULL in the record, and you get this ugly message about a user
conflict!

When BOOLS are handled as character data, this doesnt happen of course.

Anybody  got any ideas about this?
