Remi i'll do a full analysis vacuum to my DB ok.
To execute by pieces, there are many possibilities,
one would be to use pgscript.
The idea is to split your big query into smaller queries.
Remi
and , how can i do it, i mean, how can i split my big query, in the case
of only this
CREATE TABLE SPLITED AS
SELECT ST_Split(b.the_geom,z.the_geom) AS the_geom
FROM public.mapa_base_141213 b, public.all_lines_merged z;

I want to create little pieces of multipolygons from these 3 shapes
(A,B and C)=result , result with all the sections formed with the
intersection from the 3 shapes together, come on tell me , do you
understand now what i want
thanks
no never mind am not offended, am trying that you understand Ok,
here are png of my 3 multipolygon shapes, what else do you need

thanks for the quick answer Rémi, but, thats right thats one of answers,
but my idea was not complete,because there is a
3rd shape, your answer works fine for the 1st and 2dn shapes, but not
with
the 3rd, because the 3rd has not suares inside,
the 3rd shape have big triangles inside,the idea is that i need some
routine that merge or blend the spatial data and with it the attributes
of respective data, i need some ideas for do that, and am working on it,
but not sucess, please i need help, thanks for all.

Re: [postgis-users] help with the Union of 2 shp
Most likely,
in your last step,
cuadrados_parts :
there is not guaranteed type to the_geom :
it could be multi, simple, line, point, etc etc.
So if you expect polygon, use ST_CollectionExtract(the_geom,3)
Then use (ST_Dump()).geom to break appart multi polygon if you want to
(thus making something like
(ST_Dump(ST_CollectionExtract(the_geom,3))).geom AS the_geom
)
(you will need to generate an unique ID, see
http://trac.osgeo.org/postgis/wiki/UsersWikiQGIS
row_number() OVER() AS id_qgis
;-) )

Seems like If you want : for each little square, get the id of big square overlaping. If this is simply this, you don't need the intersection function, but only the intersects function : You could do something like this SELECT ss.id, bs.id , ss.geom FROM smal_square_table AS ss, big_square_table AS bs WHERE ST_Intersects(ss.geom,bs.geom)=TRUE Cheers, Rémi-C 2013/12/12 isla...@infomed.sld.cu Hi, Try pg 21 of this: http://presentations.opengeo. org/2011_FOSS4G/postgis-power.pdf That will give you the metacode.
