Using that on my kubuntu machine with no configure options except
prefix:
hiro@kgrittn-desktop:~$ /usr/local/pgsql-8.4beta2/bin/psql -U hiro
sylph
psql (8.4beta2)
Type "help" for help.

sylph=# SELECT msg_sid, hdr_from, hdr_to, hdr_subject, msg_date,
folder_id, msgnum FROM msginfo LEFT JOIN msg_folderinfo USING (msg_sid)
WHERE plainto_tsquery(E'a') @@ body_index;

Given that I can replicate this, is there some useful next step?
