This mechanism allows you to have multiple versions of PG, as well as multiple instances of the same version, installed side-by-side, and you specify the one you want with the --cluster option, which pg_wrapper understands - psql --cluster 9.1/main [....] - and in my (limited) experience it works really well. > I am just wondering because is not the first time we have to help > ubuntu users having problems locating the postgres binaries. > (Including myself the first time I installed postgres in a ubuntu > machine) > > Is the future apt.postgresql.org service also going to use this > directory for postgres binaries? It does already - my installation comes from apt.postgresql.org.
