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?
