If you're trying to store useful data in a CVS-tip installation,
it's a good idea to pay close attention to the CVS logs, particularly
http://www.postgresql.org/cgi/cvsweb.cgi/pgsql/src/include/catalog/catversion.h
which will keep you posted on initdb-forcing changes.

Or to be really safe, always do a backup before updating.
