[Spanish] RE: Re: POSTGIS - SELECT de puntos de una linea (Gustavo Jarr?n)

[Gastón Lucero]

Gustavo, seria algo similar

select st_pointn(st_exteriorring(poligono), 
generate_series(1,st_numpoints(st_exteriorring(poligono))))
Si fuera un multipolygon deberias iterar sobre los poligonos del 
multipoligono con st_geometryn, sino st_exteriorring lanza un error

Saludos espero que te sirva
Gaston
