[postgis-users] pgsql2shp on a on-the-fly request

[perikut]

hello, i am trying to make not a usual postgis to shapefile dump, as the 
geometry is created on the fly along with other calculations.

this Sql works fine, as you can see i create the geom on the fly  

select SUM(counter) as suma, astext(snapped_geom) as centroid, 
geomfromText(ST_AsText(ST_Envelope(GEOMETRYFROMTEXT('LINESTRING('||(st_xmax(snapped_geom)-2.5||' 
'||(st_ymax(snapped_geom)-2.5)||', '||(st_xmax(snapped_geom)+2.5)||' 
'||(st_ymax(snapped_geom)+2.5)||')'),4326)))) as pols from ( SELECT 
(regexp_matches(t::text, 
E'(Anguilla[\+])([0-9]+)'::text)::text[])[2]::integer as 
counter,snapped_geom from (select ST_SnapToGrid( ST_SetSRID(the_geom, 
4326), 5) as snapped_geom,array_genus from simple_datapublisher_3 where 
array_genus ~ 'Anguilla'::text group by snapped_geom,array_genus) t ) t2 
GROUP BY snapped_geom;

but when i directly put on a pgsql2shp operation, i get error like... 
Syntax error near to unexpected symbol « ( »

pgsql2shp -f /www/test -p 5432 -h host -u user -P pwd -g polygons select 
SUM(counter) as suma, astext(snapped_geom) as centroid, 
geomfromText(ST_AsText(ST_Envelope(GEOMETRYFROMTEXT('LINESTRING('||(st_xmax(snapped_geom)-2.5||' 
'||(st_ymax(snapped_geom)-2.5)||', '||(st_xmax(snapped_geom)+2.5)||' 
'||(st_ymax(snapped_geom)+2.5)||')'),4326)))) as polygons from ( SELECT 
(regexp_matches(t::text, 
E'(Anguilla[\+])([0-9]+)'::text)::text[])[2]::integer as 
counter,snapped_geom from (select ST_SnapToGrid( ST_SetSRID(the_geom, 
4326), 5) as snapped_geom,array_genus from simple_datapublisher_3 where 
array_genus ~ 'Anguilla'::text group by snapped_geom,array_genus) t ) t2 
GROUP BY snapped_geom;

I am not sure if paremeter -g (set as polygons because the resulting 
geometries are named polygons) is correctly set, but even removing it i 
allways get the same error.

I know the SQL sentence is a little complicated, just below a very basic 
structure to get an idea what is doing.

geom1, Anguilla +30||specieY+10||specieZ+5
geom2, specieX+10|| Anguilla +10
...

thanks in advance,

Pere Roca
