Dave: I did as you told. The subsite after upgrade error still occurred but the rest worked fine. but now everywhere in the code where ever
select acs_object_id_seq.nextval from dual
is used I get an error from postgres:
FEHLER: fehlender Eintrag in FROM-Klausel für Tabelle »acs_object_id_seq«
means something like: missing entry in from-clause for table acs_object_id_seq
Any idea?
