The problem is that there is no cast from bigint=>interval directly AFAICT, so 
go via text.

richardh=> select extract(epoch from now());   date_part
------------------1027593096.67471
(1 row)

richardh=> select '1970-01-01 00:00:00 GMT'::timestamp + 
((1027593096::bigint)::text)::interval;       ?column?
------------------------2002-07-25 11:31:36+01

In your case you'd replace (1027593096::bigint) with the name of your column.
