Обсуждение: Cast timestamptz to/from integer?

I work a lot with Unix times as integers, but would like to store them
in Postgres as 'timestamp(0) with time zone' for convenience and
readability. Unfortunately the syntax to translate between the two is
a little cumbersome, so I'm looking at hiding it away behind a
function - or a cast. However, the CREATE CAST docs say that I have to
be the owner of either the source or target types, which presumably
means I can't define a cast from timestamptz to int.

Is there a workaround for this?

Yep, but when you do that a lot, your statement gets extremely long. I
can create a function that'll hide the mess away, but what I'm hoping
to do is simply cast:

SELECT 982384720::timestamptz;
