Remi i dont understand what do you mean here,
You can try to analyze a bit to understand better
(for the following I consider your table doesn't contains too much data)
with the_data AS (
SELECT the_geom, ST_ISValid(the_geom) AS is_valid,
ST_IsValidReason(the_geom)
FROM ft_potencial
)
SELECT *, ST_AsText(ST_MakeValid(the_geom)) AS corrected_geom,
ST_AsText(the_geom) AS original_geometry, detail.*
FROM the_data, *ST_IsValidDetail*(the_geom) AS detail
WHERE is_valid = false
AND GeometryType(the_geom) ILIKE '%POLYGON%'
My guess : you have an invalid no-area polygon, so the makevalid function
transform it into a line
ok, but like i say above, i dont understan, please be more specific,
please, but thanks
Cheers,

Subject: [postgis-users] problem with st_makevalid and (LineString)
Hello people, i got a problem where i have no idea what can i do.
I have this table
CREATE TABLE ft_potencial
(
id_dw_ft_potencial integer NOT NULL,
id_dw_tipo integer NOT NULL,
id_dw_mes integer NOT NULL,
id_dw_municipio integer NOT NULL,
id_dw_date integer NOT NULL,
potencial real NOT NULL,
area real NOT NULL,
the_geom geometry(Polygon,4326),
CONSTRAINT ft_potencial_pkey PRIMARY KEY (id_dw_ft_potencial,
id_dw_tipo, id_dw_mes, id_dw_municipio, id_dw_date)
)
WITH (
OIDS=FALSE
);
and i want to clean the errors that it has using the function
ST_MakeValid in this way
update ft_potencial set the_geom=ST_MakeValid(the_geom);
but it always return this error
ERROR: Geometry type (LineString) does not match column type (Polygon)
********** Error **********
ERROR: Geometry type (LineString) does not match column type (Polygon)
Estado SQL:22023
what can i do to fix or clean the geometry without problems.
please help.
thanks
