I think you're wrong [ checks... ]  Yup, only b4 and up are initdb-
compatible with 8.1 final.

When in doubt, the authoritative story for this sort of thing may be
found here:
http://developer.postgresql.org/cvsweb.cgi/pgsql/src/include/catalog/catversion.h
CVS tags sharing the same catversion are initdb-compatible.
