ST_MPointFromShape takes a binary column and returns a multipoint column. The input binary column must contain the
shapefile representation of multipoint geometries. You can optionally specify a
spatial reference for the result multipoint column. The sr
parameter value must be a valid SRID or WKT string.
If a multipoint cannot be created from the input binary the function will return null
.
