Minor disaster after upgrading with cvs.

Greetings,

I've just - about 4 hours ago upgraded via cvsup and upon restarting PG
I was greated by this gem of information

02:10:26 postgres@berty:~ $ ./bin/pg_ctl -o -i start
postmaster successfully started
02:10:43 postgres@berty:~ $ FATAL 2: database was initialized with
PG_CONTROL_VERSION 0,
but the backend was compiled with PG_CONTROL_VERSION 71.
looks like you need to initdb.

02:10:50 postgres@berty:~ $

While it is not a total disaster to have to re-create the database tables,
it is something I did not forsee. Is there some quick and easy way out
of this er situation without having to do an anoyingly non-trivial amount
of work?

Thanks for everything.
