Like the geometry ST_Contains, the raster ST_Contains will use a spatial index (&& operator) if available.

Raster/Raster variants 

1. st_contains(
	rast1 raster, nband1 integer,
	rast2 raster, nband2 integer
) -> boolean

2. st_contains(
	rast1 raster,
	rast2 raster
) -> boolean

Raster/Geometry variants in raster-space 

3. st_contains(
	rast raster,
	geom geomtry,
	nband integer DEFAULT NULL
) -> boolean

4. st_contains(
	rast raster,
	nband integer,
	geom geometry
) -> boolean

Geometry/Raster variant in vector-space 

5. st_contains(
	geom geometry,
	rast raster,
	nband integer DEFAULT NULL
) -> boolean

Yeah. There's a pattern here amongst all the spatial relationship functions.
