ST_PointFromEsriJSON

ST_PointFromEsriJSON takes a string column and returns a point column. The input string column must contain the Esri JSON representation of point geometries. You can optionally specify a spatial reference for the result point column. The sr parameter value must be a valid SRID or WKT string. Any SRID defined in the input Esri JSON strings will not be used. If a point cannot be created from the input string the function will return null.
