Re: PostgreSQL upgrade -> fails to start server

Ok, IIRC the reason you need to initdb is because indexes use your specific
locale to work. Without knowing the locale, indexes can't be used.

That said, it seems to be a bit strict to refuse to start the server.

In any case, there is a program pg_controldata which dumps the current
locale. It may help to determine if you edit pg_control properly.

Once you can start it, pg_dumpall and restart. Ofcourse, if you have
backups...

In any case, as a last resort you can try pgfsck
(http://svana.org/kleptog/pgfsck.html). It ignores your locale and so may be
able to recover some of your data.

Hope this helps,
