Can I use return value of INSERT...RETURNING in another INSERT?

Viewed 144326

Is something like this possible?

INSERT INTO Table2 (val)
VALUES ((INSERT INTO Table1 (name) VALUES ('a_title') RETURNING id));

like using the return value as value to insert a row in a second table with a reference to the first table?

DO $$
DECLARE tableId integer;
BEGIN
  INSERT INTO Table1 (name) VALUES ('a_title') RETURNING id INTO tableId;
  INSERT INTO Table2 (val) VALUES (tableId);
END $$;

Tested with psql (10.3, server 9.6.8)
