Postgresql: Intersection between polygons returns lines and points

Question

I am working on a spatial query and have two tables with features of Geometrytype ONLY Polygon or Multipolygon:

ZONING TABLE:

select ST_GeometryType (geom), count (*) 
    from    
        legislacao_urbanistica_municipal.prod_lu_zon_zoneamento
group by ST_GeometryType (geom)

This query returns to me:

"St_multipolygon" "13"

"St_polygon" "606"

SQUARE TABLE

select ST_GeometryType (geom), count (*) 
    from    
        cadastro_tecnico_municipal.prod_ct_ctm_quadra_ctm
group by ST_GeometryType (geom)

This query returns to me:

"St_multipolygon" "110"

"St_polygon" "17661"

Note that there is only Polygon or Multipolygon.

However, when I give a St_intersection, my return contains points, lines and polygons and multis.... Of all! And it’s getting in my way:

This is the query that makes the intersection:

create materialized view legislacao_urbanistica_municipal.lu_lei_7166_zoneamento_quadra_vw as
select  row_number() over (order by id_tipo_zoneamento) as id,
        ST_Intersection(ST_Multi(quadra.geom),ST_Multi(z_7166.geom)) as geom,
        z_7166.id_tipo_zoneamento
    from    legislacao_urbanistica_municipal.prod_lu_zon_zoneamento as z_7166,
            cadastro_tecnico_municipal.prod_ct_ctm_quadra_ctm as quadra
    where ST_Intersects (z_7166.geom , quadra.geom)

And the return of her geometry types:

select ST_GeometryType (geom), count (*) 
    from    
        legislacao_urbanistica_municipal.lu_lei_7166_zoneamento_quadra_vw
group by ST_GeometryType (geom)

"St_geometrycollection" "195"

"St_linestring" "3"

"St_multilinestring""41"

"St_multipoint" "2"

"St_multipolygon" "783"

"St_point" "13"

"St_polygon" "18782"

The problem is that from this table I make another query of Intersection and, as it has Geometrycollection in it, Pgadmin gives me error:

SELECT  h.id_zona_homogenea_tgc, 
        z.id_tipo_zoneamento,
        z.sigla_zoneamento
    FROM    tributario.prod_tr_lim_zona_homogenea_tgc as h, 
            (
                select  a.id_tipo_zoneamento, 
                        b.sigla_zoneamento, 
                        a.geom 
                    from    legislacao_urbanistica_municipal.lu_lei_7166_zoneamento_quadra_vw a,
                            legislacao_urbanistica_municipal.prod_lu_zon_tipo_zoneamento b
                    where a.id_tipo_zoneamento = b.id_tipo_zoneamento
            ) as z
    where   ST_Intersects(h.geom,z.geom)
    group by h.id_zona_homogenea_tgc, z.id_tipo_zoneamento, z.sigla_zoneamento
    ORDER BY id_zona_homogenea_tgc

I’ve tried some solutions (Dump, cast, Multi), but it’s not rolling. Someone knows the reason and some solution?
