Actually, it is an RTFM...

>From the manpage of pgbuiltin (my postgres version is 6.2.1):

     For the date_part() and  date_trunc()  functions,  arguments
     can   be  `year',  `month',  `day',  `hour',  `minute',  and
     `second',  as  well  as  the  more  specialized   quantities
     `decade',   `century',   `millenium',   `millisecond',   and
     `microsecond'.  date_part() allows `dow' to  return  day  of
     week  and  `epoch' to return seconds since 1970 for datetime
     and 'epoch' to return total elapsed seconds for timespan.

So...
