So should varchar(10000000) be returned as VARCHAR or LONGVARCHAR?

Right now we return 0 for the precision of text or varchar without length.
Perhaps we should return something else for that similar to how we changed
the result of ResultSetMetaData.getColumnDisplaySize to return
Integer.MAX_VALUE instead of -1 for types without lengths.
