#3277 closed defect (fixed)

Raster import fails from different schema with constraint

Reported by: jczaplewski Owned by: Bborie Park
Priority: medium Milestone: PostGIS 2.2.2
Component: raster Version: 2.1.x
Keywords: raster, restore Cc:


When a raster table is not in the schema public and has a raster_constraint_pixel_types constraint, the following error is thrown when importing from pg_dump:

ERROR:  function st_bandmetadata(public.raster, integer[]) does not exist
LINE 1:  SELECT array_agg(pixeltype)::text[] FROM st_bandmetadata($1...
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.
QUERY:   SELECT array_agg(pixeltype)::text[] FROM st_bandmetadata($1, ARRAY[]::int[]); 
CONTEXT:  SQL function "_raster_constraint_pixel_types" during inlining

It seems that the issue is that postgres is unable to find the proper spatial functions, and indeed if you alter the line

   SET search_path = rasters, pg_catalog;


   SET search_path = public, rasters, pg_catalog;

the import of the dump works as expected. You can reproduce this error with the following example:


CREATE TABLE rasters.my_rasters (
  id serial NOT NULL,
  rast raster,
  CONSTRAINT enforce_pixel_types_rast CHECK ((public._raster_constraint_pixel_types(rast) = '{16BSI}'::text[]))

INSERT INTO rasters.my_rasters (rast) (
	SELECT ST_AsRaster(
			'LINESTRING(-108 30, -87 43)'
		, 4326),
		150, 150, '16BSI'

pg_dump -C test > ~/Downloads/test.sql && dropdb test && psql < ~/Downloads/test.sql

Note for 2.2.2 - one would need to run the script explicitly as noted in FAQ -

For PostGIS 2.3, this will be automatic and not require script running
