Try the functions reference in the postgresql manual--there's a lot of
information about Pgsql date/time functions there, but in your case, no
function is needed--overloaded operators will work fine.

select yourdate - '0000-01-01'::date from yourtable;

seems to work just fine, and returns an integer.

Both PostgreSQL and MySQL say there have been  730485 between 1/1/0
and 1/1/2000. Something we all can agree on? :-)

Good luck w/your app,
