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...
