It adds to P ostgre SQL several spatial data types and over 300 functions for working with these spatial types. It does for P ostgre SQL what Oracle Spatial/Locator does for Oracle, what IBM DB2 /Information spatial DataBlades do for DB2 and Informix, and what geometry/geography types packaged in Microsoft SQL S erver 2008+ do for SQL S erver.
