I am getting a little confused in casting 'infinity'.

It seems that 'infinity' still can't be casted to a date. :-(

But I tried the following casts, but I am not sure the results are consistent.

instrumentation=> SELECT 'infinity'::date;
ERROR:  invalid input syntax for type date: "infinity"


instrumentation=> SELECT 'infinity'::timestamptz;
 timestamptz
-------------
 infinity
(1 row)

instrumentation=> SELECT 'infinity'::timestamptz::date;
 date
------
      <-- this blank I determine was a NULL.
(1 row)


Is this correct?  Shouldn't it also return an error?

Richard Broersma Jr.
