Actually, up until the 7.4 release, the array literal syntax was the
*only* syntax (i.e. '{...}'). The newer array constructor expression
(i.e. ARRAY[...]) does not yet support creating empty arrays -- there
are some non-trivial technical difficulties to be solved. Unfortunately
that won't change in the upcoming 7.5 either :( -- perhaps for 7.6.
