Question

这似乎是一个转储问题。但是，我有这个运行PostGIS的遗留数据库（但现在不再存在），并且转储中仍然有许多PostGIS特定代码。像这样的东西：

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

和

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;
                ...

（你明白了）。

我没有丢失任何与GIS相关的数据，我不应该这样做。我在倾销和重装方面也很好，但不这样做显然会更好。

FWIW，因为它似乎不是一个正式的卸载脚本（我很清楚），这是我最后运行的脚本，用于删除由所创建的所有数据类型和函数PostGIS的：

    var hub = $.connection.hub,
        serverEventsHub = $.connection.serverEventsHub,
        server = serverEventsHub.server,
        client = serverEventsHub.client;

    hub.disconnected(function () {
        window.setTimeout(function () { 
            hub.start();
        }, 5000);
    });
   hub.start();
