1.	If we stick with the separate data partition which
    i think is quite ok, we should be nice enough to create
    a symlinc between the place where postgresql expects 
    to find its files (/var/opt/postgresql/data) and the actual 
    /data partition.
2.	We should try to initialize the db cluster after install
    issuing an `initdb -D /var/opt/postgresql/data` command
    with user postgres. Since we have some env variables maybe
    the `-D blah blah blah` is redundant, but it cannot hurt to be safe
    
3.	We might want to add a `-i -o -e` ending to the line that
    starts the postgresql daemon meaning `i want inet connections
    and please use european date formats`. Although PG guys advise 
    to use the new way to tel pg that (postmaster.opts or so), I
    stick with the old way if possible. Anyway the `-o -e` must go
    to the run line.
