   ### NixOS - usage:
   ==================
 
-    services.posgresql.extraPlugins = [ pkgs.postgis.v_1_5_1 ];
-
-    or if you want to install 1.5.x and 1.3.x at the same time (which works
-    because the .sql and .so files have different names):
-
-    services.postgis.extraPlugins = [ (pkgs.buildEnv {
-          name = "postgis-plugins";
-          ignoreCollisions = 1; # scripts will collide - but there are aliases with version suffixes
-          paths = [ pkgs.postgis.v_1_3_5 pkgs.postgis.v_1_5_1 ];
-        })];
-
-    By now it is only supported installing one of the 1.3.x verions because
-    their shared libraries don't differ in naming.
-
+    services.postgresql.extraPlugins = [ (pkgs.postgis.override { postgresql = pkgs.postgresql94; }).v_2_1_4 ];
 
 
   ### important Postgis implementation details:
···
 
       CREATE FUNCTION [...]
               AS '[..]liblwgeom', 'lwhistogram2d_in' LANGUAGE 'C' IMMUTABLE STRICT; -- WITH (isstrict);
-    
+
    where liblwgeom is the shared library.
    Postgis < 1.5 used absolute paths, in NixOS $libdir is always used.
 
    Thus if you want to use postgresql dumps which were created by non NixOS
    systems you have to adopt the library path.
