different catalogue version numbers?

Hi,

I suspect this is actually a Debian question, but I thought someone here
could point me in the right direction in interpreting an error message. I
was working with one of the betas of Postgresql 7, and thought it would be
nice to catch some of the bugfixes. So, I installed the release version
(provided as a Debian package). Now, I can't get to my data:

$ 000602.17:24:31.191 [5066] DEBUG: Data Base System is starting up at Fri

000602.17:24:31.217 [5066] FATAL 2: database was initialized with
CATALOG_VERSION_NO 200003141,
but the backend was compiled with CATALOG_VERSION_NO 200005041.
looks like you need to initdb.

Startup failed - abort

Do I need to restore the dumped data? I can do that, but mostly I'm curious
about what happened.
