 NOTICE:
-     This version will works only with postgresql version 7.3 and above
+     This version will works only with postgresql version 7.4 and above
      because of changes in interface of function calling and in system
      tables.
+     
+     If you want to index varchar attributes, you have to index using
+     the function text(<varchar>):
+     Example:
+       CREATE TABLE test ( a varchar(23) );
+       CREATE INDEX testidx ON test USING GIST ( text(a) );
