PlaidCloud expressions and filters provide use of most non-administrative PostGIS methods. PostGIS methods are accessed by prefixing the standard method name with
ST_CPAWithin(geometry track1, geometry track2, float8 maxdist);
func.ST_CPAWithin(geometry track1, geometry track2, float8 maxdist)
PostGIS Official Documentation for this method can be found here.
Additional capabilities and usage examples can be found in the PostGIS documentation.
