Ok I progressed a bit, now with psql I can see my main db and some tables, but they don't contain many rows.
Noticable messages in the logfile :
2008-02-05 18:01:18 CET LOG: transaction ID wrap limit is 1073748480, limited by database "wowdbu"
2008-02-05 18:01:18 CET LOG: autovacuum: processing database "postgres"
2008-02-05 18:01:18 CET LOG: incomplete startup packet
2008-02-05 18:02:08 CET LOG: incomplete startup packet
I tried a pg_dumpall and it fails quickly with this error :
pg_dump: SQL command failed
pg_dump: Error message from server: ERROR: could not access status of transaction 3270404
DETAIL: could not open file "pg_clog/0003": No such file or directory
pg_dump: The command was: SELECT tableoid, oid, proname, prolang, pronargs, proargtypes, prorettype, proacl, pronamespace, (SELECT rolname FROM pg_catalog.pg_roles WHERE oid = proowner) as rolname FROM pg_proc WHERE NOT proisagg AND pronamespace != (select oid from pg_namespace where nspname = 'pg_catalog')
pg_dumpall: pg_dump failed on database "postgres", exiting
I read about things like zeroing missing pg_clog files... Can it work ? I thought clog files were about transactions, but I don't care about last transactions, even data from 1 month ago would be enough for me.
So what can I do from there ?

What's the full pg_controldata output? Can you send the pg_control file
as a binary attachment?
