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?
------------------------

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