Hi guys

I am getting the following:

postgres@newcollab:/usr/lib/postgresql/9.0/bin$ ./pg_upgrade -b /usr/lib/postgresql/8.4/bin/ -B /usr/lib/postgresql/9.0/bin/ -d /var/lib/postgresql/8.4/main -D /var/lib/postgresql/9.0/main
sh: /usr/lib/postgresql/9.0/bin/pg_config: not found

#locate pg_config
/usr/share/locale-langpack/en_GB/LC_MESSAGES/pg_config-8.4.mo
/usr/share/postgresql-common/t/140_pg_config.t
