This fix is not correct because the Jdbc2 classes must be compilable by a
1.2 and 1.3 JDKs which do not have Types.BOOLEAN available. A fix of this
kind would need to go into one of the Jdbc3 classes which are only
compiled by >= 1.4 JDKs. I also don't believe your fix is necessary.
org.postgresql.test.jdbc3.TypesTest has the following test in it
pstmt.setObject(2, null, Types.BOOLEAN) and it works fine. Could you be
more clear on what your problem was (with a stacktrace)? If you are using
a jdbc2 version driver then it won't work and you need to use a jdbc3
driver.
