 <p>
 In addition to standard SQL types, this method identifies MySQL 4.1's geometric
 datatypes and creates attribute types accordingly.  This happens when the
 datatype, identified by column 5 of the ResultSet parameter, is equal to
 java.sql.Types.OTHER.  If a Types.OTHER ends up not being geometric, this
 method simply calls the parent class's buildAttributeType method to do something
 with it.

 <p>
 Note: Overriding methods must never move the current row pointer in the
 result set.
