The GIS function ST_Validate takes ad input a geometry and verifies that
- is compliant with the Well-Known Binary (WKB) format and Spatial
  Reference System Identifier (SRID) syntax.
- is geometrically valid.
If the input is valid return it, else it returns NULL. The use case of
this function is to filter out invalid geometry data.
