CVS, initdb and catalog version

Hi,

I updated my source code from CVS and it looks like it creates a problem
because now, the server won't come up because of this error:

Starting postgresql service: + su -l postgres -c '/usr/local/bin/pg_ctl  -D /usr/local/var/lib/pgsql/data -o -i -p /usr/local/bin/postmaster start'
postmaster successfully started
FATAL 2:  database was initialized with CATALOG_VERSION_NO 200105101,
	but the backend was compiled with CATALOG_VERSION_NO 200105145.
	looks like you need to initdb.

and then:

initdb: The directory /usr/local/var/lib/pgsql/data exists but is not empty.
If you want to create a new database system, either remove or empty
the directory /usr/local/var/lib/pgsql/data or run initdb with
an argument other than /usr/local/var/lib/pgsql/data.

So does that mean that every time I update the CVS code I have to trash
my existing data? Not that it's really a problem yet, mind you. When I
have real data that I need to keep, I'll move to 7.1.1.
