I think you've been bit by the RelFileNodeEquals bug we found on Monday.
One of the known possible effects of that bug is that a VACUUM can write
blocks of system-catalog tables into the same catalog of a different
database.
You should probably write off your databases as toast ... update to
beta3 and do an initdb. Sorry about that ...
