I'm trying to use the function ST_Extrude() in Postgres 9.2. I enabled the PostGIS 2.2.0 extension and the PostGIS_SFCGAL extension (which carries the ST_Extrude function).
I can see the function in my list of functions (see snapshot), but I cannot use it.
When I try following SQL code:
CREATE TABLE house AS SELECT id, ST_Extrude(geog, 0, 0, 5) as geom FROM houses WHERE id = 1500;
I get an error that the function ST_Extrude does not exist:
Does someone know what is going wrong here?
