More efficient DELETE ... ?

This looks painful ...

DELETE FROM webhit_referer_raw     WHERE oid IN ( SELECT w.oid                      FROM webhit_referer_raw w,
referrer_datar                     WHERE stat_date < 'Jan 17 2000 15:05:00'                       AND w.referrer_url =
r.referrer);
 

But, reading through the man page, it looks like this about the only way
of doing it?  Or am I missing something as obvious as the UPDATE I asked
about the other day? :(
