just updated to R1 if you have this problem here is the fix...
2010-11-07 13:49:00 PST FATAL: could not create lock file "/var/run/postgresql/.s.PGSQL.5432.lock": Permission denied
also just a informational for the how-to you can also install
external_pid_file = '/tmp/8.3-main.pid'
unix_socket_directory = '/tmp/'
#ssl = true (dont forget that from the OP)
apt-get install pgadmin3
if your like me and dont like to deal with command line database managment
or you can alternately give posgres permissions everywhere either way.. this was just faster
