Can't start portgresql after F15 -> F16 upgrade

[Deron Meranda]

Yes, it most likely has to do with upgrading the version of PostgreSQL
to 9.1, and any previously-existing databases not being
version-compatible. You can see the error messages if you...

grep pg_ctl /var/log/messages


If you didn't have any databases you need to keep, then just delete
the old data directory and re-initialize it.

# rm -fr /var/lib/pgsql/data/*

# su - postgres
$ pg_ctl init
