Hello hackers,

Please look at an internal error produced with the following script added
to src/test/regress/sql/graph_table.sql:
CREATE TABLE x(a int);
SELECT * FROM x, GRAPH_TABLE (myshop MATCH (c IS customers) ->(l IS orders | wishlists) COLUMNS (c.name, x.a AS a));

ERROR:  XX000: plan should not reference subplan's variable
LOCATION:  finalize_plan, subselect.c:3159

Best regards,
Alexander
