different empty array syntax requirements

How is that one pgsql build (both are 9.5.2) has different casting behavior for empty arrays:


ericmj=# select ARRAY[]::text[];
 array
-------
 {}
(1 row)

ericmj=# select (ARRAY[])::text[];
 array
-------
 {}
(1 row)


--VS--


pedcard=# select ARRAY[]::text[];
 array
-------
 {}
(1 row)

pedcard=# select (ARRAY[])::text[];
ERROR:  cannot determine type of empty array
LINE 1: select (ARRAY[])::text[];
                ^
HINT:  Explicitly cast to the desired type, for example ARRAY[]::integer[].
