Hi, I am seeing this error with 8.3beta3 on debian unstable:
2007-11-28 15:15:46 CET ERROR: cached plan must not change result type 2007-11-28 15:15:46 CET STATEMENT: SELECT s.*, coalesce(d.firstname||' ','')||coalesce(d.lastname,'') as person_name, person_url(d.id_person), t.person_type, t.id_person from show s left join person_to_show t using (id_show) left join person d using (id_person) where s.id_show = $1 The query is sent by a mod_perl app and a restart of apache2 fixes it. Let me know if you need more info. Cheers, ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
