This does appear to be a gotcha, as the following returns a negative
integer as expected:

postgres=# SELECT -2147483648;
  ?column?
-------------
 -2147483648
(1 row)

postgres=# SELECT pg_typeof(-2147483648);
 pg_typeof
-----------
 integer
(1 row)

And just in case...

postgres=# SELECT pg_typeof(test.my_num) FROM (SELECT -2147483648) AS
test(my_num);
 pg_typeof
-----------
 integer
(1 row)

So it's affected by the cast operator?
