 Priority:  high    |   Milestone:  PostGIS 2.1.5
Component:  raster  |     Version:  2.1.x

Comment(by rtorre):

 Since the purpose of the constraint is to check for equality of `numeric`
 values, something like
 {{{
 CHECK abs(st_scalex(the_raster_webmercator) - (attr)) <= delta
 }}}

 should be more appropriate, with `delta = 1e-10` for instance.
