why complicate so much ? this is a single sql query. It really shocks me, how people easily lean on plpgsql and for/loops - which are times slower than simple sql query:
CREATE FUNCTION unnest(anyarray) RETURNS SETOF anyelement AS
$_$
SELECT ($1)[i] FROM generate_series(array_lower($1,1),array_upper($1,1)) i;
$_$
LANGUAGE sql IMMUTABLE;
