The idea is to have one command for server control. By my opinion init
logically belongs to group of command like start/stop. It is also
possible to add parameter for init+start in one command and so on.
If you look on ZFS you have only two commands to manage everything, it
is easy and you can start to use ZFS very quickly. I think this patch
increase usability/adoption od postgreSQL for newbies.
And second big advantage is that it would be possible easily extend
pg_ctl to cope with different postgresql versions (e.g. "pg_ctl -v 8.2
-D . init"). There is no reason why pg_ctl couldn't start different
postgreSQL version depends on PG_VERSION in data directory.
