Just wasting space, I'm afraid. You may want to apply the patch at
http://www.ca.postgresql.org/mhonarc/pgsql-patches/2001-06/msg00061.html
However, if the database consists of several small tables and not one
huge one, I'm not sure why VACUUM's WAL log might grow so long. The
log should be truncatable after each table is vacuumed, even without
the patch.
