Mandarack 10.2 Now I can't access the database. bash-3.00$ postmaster -D /var/lib/pgsql/data/ FATAL: database files are incompatible with server DETAIL: The data directory was initialized by PostgreSQL version 7.4, which is not compatible with this version 8.0.1.

How to I upgrade the data set to access?
