Hur man filtrerar postgis-frågor baserat på ST_GeometryType

Din fråga är ganska stor och på grund av bristen på indrag och en fungerande fiol är det svårt att veta var problemet ligger. För ytterligare frågor överväg att skapa ett minimal reproducible example . Jag märkte också att du i en enda fråga omvandlar geometrier 18 gånger (!) fram och tillbaka mellan 31467 och 25832 . Är det verkligen nödvändigt? Tänk på att omvandlingar kan ta tid och kommer säkert att sakta ner dina frågor. Gör nödvändiga transformationer, om möjligt, i ursprunget eller i slutet av en kedja av funktioner. Till exempel istället för

WITH j (point) AS(
  VALUES ('POINT(1 2)'::geometry)
)  
SELECT st_astext(
ST_MakeEnvelope(
  ST_X(ST_Transform(ST_SetSRID(point,31467),25832)),
  ST_Y(ST_Transform(ST_SetSRID(point,31467),25832)),
  ST_X(ST_Transform(ST_SetSRID(point,31467),25832))+10,
  ST_Y(ST_Transform(ST_SetSRID(point,31467),25832))+10),2)
FROM j;

.. överväg detta:

WITH j (point) AS(
  VALUES (ST_SetSRID('POINT(1 2)'::geometry,31467))
)  
SELECT 
 ST_Transform(    
   ST_MakeEnvelope(
     ST_X(point),ST_Y(point),ST_X(point)+10,ST_Y(point)+10,31467),
  25832)
FROM j

Resultaten kan vara något annorlunda, men beroende på ditt användningsfall spelar det ingen större roll. Prova båda metoderna och om möjligt håll din kod ren.

Med det sagt kan du använda ST_NumGeometries för att räkna antalet geometrier i en kolumn:

SELECT 
  ST_NumGeometries('MULTIPOLYGON (((40 40, 20 45, 45 30, 40 40)),((20 35, 10 30, 10 10, 30 5, 45 20, 20 35)))'::geometry),
  ST_NumGeometries('POLYGON((40 40, 20 45, 45 30, 40 40))'::geometry);

 st_numgeometries | st_numgeometries 
------------------+------------------
                2 |                1

Så din fråga bör se ut så här:

WITH j AS (
      SELECT DISTINCT
           ST_MakeEnvelope(
                    ST_X(ST_Transform(ST_SetSRID(point,31467),25832)),
                    ST_Y(ST_Transform(ST_SetSRID(point,31467),25832)),
                    ST_X(ST_Transform(ST_SetSRID(point,31467),25832))+10,
                    ST_Y(ST_Transform(ST_SetSRID(point,31467),25832))+10) AS geom_int1,
