BIT vs boolean

According to the jdbc doc's one should set a BIT value in a prepared statement
using the setBoolean function.  So I think the following should work:

        stat = con.createStatement();

        stat.execute( "CREATE TABLE bitTable( b BIT )" );

        pstat = con.prepareStatement( "INSERT INTO bitTable( b ) VALUES( ? )" );

        pstat.setBoolean( 1, true );

        pstat.execute();

However with pgsql-jdbc 7.3.3 build 110, I get the following error:

Exception in thread "main" java.sql.SQLException: ERROR:  Cannot parse 't' as a
binary digit

Is setBoolean is just printing true or false into a string and expecting the
database side to parse it?  Maybe it should check the type of the column to
determine if the boolean value should be printed as true/false or 0/1 (or
whatever BIT is expecting to see).
