However, the ODBC driver's parsing is desperately inadequate anyway
(it fails to handle nested function calls properly). It might well be
that fixing that will entail doing enough work that "= NULL" could be
recognized without much more work.
On the third hand, pushing the kluge out to the ODBC driver doesn't make
it any less a kluge...
