PostGISレガシー（プレ拡張機能）をアンインストールする方法

Question

これはダンプのように思えるかもしれません。しかし、私はPostGISを実行していた（しかし、もうこれ以上ではない）このレガシーデータベースを持っていて、まだPostGIS固有のコードをたくさん持っています。このようなもの：

CREATE TYPE box2d (
    INTERNALLENGTH = 65, 
    INPUT = box2d_in, 
    OUTPUT = box2d_out, 
    ALIGNMENT = int4, 
    STORAGE = plain 
); 

と

CREATE FUNCTION _st_concavehull(param_inputgeom geometry) RETURNS geometry 
    LANGUAGE plpgsql IMMUTABLE STRICT 
    AS $$ 
     DECLARE 
     vexhull GEOMETRY; 
     var_resultgeom geometry; 
     var_inputgeom geometry; 
     vexring GEOMETRY; 
     cavering GEOMETRY; 
     cavept geometry[]; 
     seglength double precision; 
     var_tempgeom geometry; 
     scale_factor integer := 1; 
     i integer; 

     BEGIN 

       -- First compute the ConvexHull of the geometry 
       vexhull := ST_ConvexHull(param_inputgeom); 
       var_inputgeom := param_inputgeom; 
       ... 

（あなたがアイデアを得ます）。

私はGIS関連のデータを失うのは問題ありません。私はダンピングとリロードもうまくいっていますが、そうしない方が明らかです。すべてのデータ型と機能を削除するには、これは私が最後に実行されていたスクリプトです、（私の知ること）公式アンインストールスクリプトがあるとは思えないので、

おかげ
