How to assign cypher result to pgsql variable?

[NathanFrund]

Hello!

I have a pretty basic cypher function whose result I'd like to assign to a pgsql variable.

Here is the mentioned query.

LOAD 'age';
SET search_path = ag_catalog, "$user", public;

SELECT exists
FROM cypher('test_graph', $$
    MATCH (n:Node)
    RETURN exists((n)-[:START]->())
$$) as (exists agtype);

I'm stumped.

In a way, I hope that the answer is obvious, but not too obvious!
