Since this is the novice list, I will add that that is a round-about way
of declaring the table.

CREATE TABLE current_academic_year
(
    year_id        INT     PRIMARY KEY REFERENCES academic_years,
    active        BOOLEAN    NOT NULL UNIQUE
);
does the same and is easier to read.

Also, your capitalisation of table names won't be preserved, because you
don't double-quote them.
