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 type2007-11-28 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_showt 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,
