You can solve it using:
euler=# select '+8:00'::interval;
interval
----------
08:00:00
(1 registro)
euler=# select '-8:00'::interval;
interval
-----------
-08:00:00
(1 registro)
As pointed by Tom in an ancient thread [1], I agree that we could add + and @
unary operator for interval datatype. Unfortunately, such a patch has not been
proposed yet.
