I have upgraded from PostgreSQL 7.0.2 to 7.1beta4. I am trying to convert a
database from the older version to work in the newer version. Unfortunately
ALL I have is the base directory zipped up containing all the tables, keys,
sequences, etc. Is there a way to convert this and have it work with
7.1beta? At the very least, is there a way for me to use a 7.0.2
installation to reinstate this database and use pg_dumpall?

Thanks very much for any help!

You have to use 7.0.x to read the 7.0 database.

Restore a 7.0.x installation.
Unzip your data directory back to its proper place.
Use 7.0.x pg_dumpall to save your data to a flat file.
Remove your data directory
Install 7.1x
Run initdb to create a new database structure.
Use psql to read in the flat file dump and recreate your data.

You mean just $PGDATA/base?  Not all of $PGDATA?  If so, sorry, but you
are flat outa luck.  You should've saved pg_log too...
