I'm using 8.1 from CVS head of about two days ago.
Extra columns seem to be on sum(plays.length), videos.path, videoid
create or replace view niceplays as SELECT count(*) AS plays,
summary("substring"(v.path, '[^/]+$'::text), 50) AS filename,
avg(p.length)::interval(0) AS avg, sum(p.length)::interval(0) AS sum,
(( SELECT now() - plays.playtimestamp
FROM plays
WHERE plays.videoid = v.videoid
ORDER BY plays.playid DESC
LIMIT 1))::interval(0) AS lastplay
FROM plays p
LEFT JOIN videos v USING (videoid)
WHERE p.length <> '00:00:00'::interval AND v.path ~~
'/home/allan/TransGaming_Drive/libp/%'::text
GROUP BY v.path, v.videoid
ORDER BY sum(p.length::interval(0)) DESC;
allan=# select * from niceplays;
plays | filename | avg | sum | lastplay
