hello,
i think there's a simple error in the "isWritable" method of the
ResultSetMetaData class in the jdbc2 postgresql driver. the isWritable method
looks like this:

public boolean isWritable(int column) throws SQLException
{
        if (isReadOnly(column))
                return true;
        else
                return false;
}

and isReadOnly looks like this:

public boolean isReadOnly(int column) throws SQLException
{
        return false;
}

hence, isWritable() will always return false. this is something of a problem
:) just switch the booleans in isReadOnly and everything should work just
fine. i have verified this in the 7.1.3 source, and it appears to work the
same way in at least 7.1.2 as well.

let me know if i can provide further information.

thanks,
ian wehrman
