Postgres creates a table with an array of foreign keys

Question

I am making a table called "routes". I want it to be able to contain a list of flights in it. Flight details are shown in the flight tables. I want the “flight” to be an array of foreign keys from the flight table. So, I have this code:

CREATE TABLE routes (
id SERIAL PRIMARY KEY,
flight integer[] ELEMENT REFERENCES flights,
user CHARACTER VARYING(50)
);

But this gives an error:

ERROR:  syntax error at or near "ELEMENT"
LINE 2:     id SERIAL PRIMARY KEY, flight integer[] ELEMENT REFERENC...

I am using psql (9.3.10)

I used this: http://blog.2ndquadrant.com/postgresql-9-3-development-array-element-foreign-keys/ as a link, but when I copy this syntax it gives this error.

This is the syntax that I use as a reference:

CREATE TABLE races (
   race_id integer PRIMARY KEY,
   title text,
   race_day DATE,
   ...
   practice1_positions integer[] ELEMENT REFERENCES drivers,
   practice2_positions integer[] ELEMENT REFERENCES drivers,
   practice3_positions integer[] ELEMENT REFERENCES drivers,
   qualifying_positions integer[] ELEMENT REFERENCES drivers,
   final_positions integer[] ELEMENT REFERENCES drivers
);
