Jak naprawić „Otwór leży poza skorupą”

Dostałem zestaw danych z kształtami wielokątów, w którym geometria została zaktualizowana przez wtyczkę QGIS „ Geometry Updater ”. Teraz mam problem, że w PostGIS otrzymuję nieprawidłowe geometrie z komunikatem o błędzie „Otwór leży poza powłoką” . Ale obserwując geometrię w QGIS, faktycznie istnieją dwa kształty, gdzie jeden jest główną geometrią, a drugi (prawdopodobnie) otwór.

Myślałem, że powodem tego było ustawienie typu geometrii ST_Polygon. Ale nawet po zmianie na ST_MultiPolygonten błąd nadal występuje. Ktoś ma pomysł, jak to naprawić? Również ręcznie w QGIS byłoby dobrze.

EDYTOWAĆ:

To jest oryginalny WKT kształtu na zdjęciu (przed zmianą na ST_MultiPolygon):

Próbowałem z narzędziem „Make Geometries Valid” OpenJUMP i zwraca poprawioną geometrię jako multipolygon. OpenJUMP korzysta z własnej funkcji makeValid. Nie wiem, czy QGIS ma równoważną funkcję, ale ponieważ masz już tę funkcję w PostGIS, możesz po prostu użyć ST_MakeValid http://postgis.net/docs/ST_MakeValid.html .
