Examples

SELECT tbl1.column1, tbl2.column1, tbl1.column2 &> tbl2.column2 AS overright
FROM
  ( VALUES
	(1, 'LINESTRING(1 2, 4 6)'::geometry)) AS tbl1,
  ( VALUES
	(2, 'LINESTRING(0 0, 3 3)'::geometry),
	(3, 'LINESTRING(0 1, 0 5)'::geometry),
	(4, 'LINESTRING(6 0, 6 1)'::geometry)) AS tbl2;

 column1 | column1 | overright
