There are a number of ways. I tend to rely on the binary equivalence
between int4 and abstime:

regression=# select now()::abstime::int4;
?column?
-----------
991145365
(1 row)

regression=# select 991145365::int4::abstime::timestamp;
?column?
------------------------
2001-05-29 10:09:25-04
(1 row)

but the more officially supported way to do the former is
date_part('epoch', timestamp), and I think there is also an
Approved Way to do the latter. (Thomas?)
