Description
In the ISO spec, ST_Centroid(empty_geometry) returns NULL, but in the Java code it returns an empty geometry. This is fixed for Velox/native in https://github.com/facebookincubator/velox/pull/15985 , but should also be fixed in Java.
Expected Behavior
ST_Centroid(ST_GeometryFromText('LINESTRING EMPTY')) IS NULL
Current Behavior
ST_IsEmpty(ST_Centroid(ST_GeometryFromText('LINESTRING EMPTY')))
Possible Solution
The ST_Centroid function should check for an empty input geometry and return null.
Steps to Reproduce
SELECT ST_Centroid(ST_GeometryFromText('LINESTRING EMPTY'))
