ST_MPointFromGeoJSON takes a string column and returns a multipoint column. The input string column must contain the
GeoJSON 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 string the function will return null.
