8.0 beta4: Exception with setBoolean on char column

The web page http://www.postgresql.org/news/235.html  says report
any/all problems in 8.0 to this address, so...

The following java code works fine on 7.4:

=20

                        Class.forName("org.postgresql.Driver");

                        Connection conn =3D
DriverManager.getConnection("jdbc:postgresql://localhost:5432/postgresdb
","xxx","");

=20

                        Statement stmt =3D conn.createStatement();

                        stmt.execute("CREATE TABLE tt (ans char(1))");

                        stmt.close();

=20

                        PreparedStatement pstmt =3D
conn.prepareStatement("INSERT INTO tt (ans) VALUES (?)");

                        pstmt.setBoolean(1, false);

                        pstmt.executeUpdate();

=20

But, in 8.0.0beta4 on we get:

=20

OS =3D Windows XP Pro

Java version 1.5.0-b64

JDBC driver: pgdev.307.jdbc3.jar

There is no problem with setString(1,"0") or when tt column is declared
bool.

=20

Also noted that on 8.0, trying to do a setString(1, "0") on a bool
column throws  "column "ans" is of type boolean but expression is of
type text" where in 7.4 there is no problem.

Thanks.
