Assuming that value is epoch date,
$ psql test -c "select date(1051156800)"
date
------------
2003-04-24
(1 row)
$ psql test -c "select date(1053316800)"
date
------------
2003-05-19
(1 row)
$ psql test -c "select date(0)"
date
------------
1969-12-31
(1 row)
$ psql test -c "select date(86400)"
date
------------
1970-01-01
(1 row)
Then wouldn't something along the lines of:
SELECT * from person_detail WHERE field='2' AND value between
date(1000000001) and date(1104555600); work....
