You may want to reread the section on jobs in the shell manual.  ctrl-z
puts the process to sleep, it doesn't kill it.  So, doing a ctrl-z just
put the postmaster to sleep in the background.  A ps -ef would have
shown you that it was in fact still there waiting for you to tell it
what to do next.  To get it to run in the background to needed to do a
bg command after your ctrl-z.

As for the IPv6, it could be the kernel doesn't have IPv6 loaded. Maybe
kernel module needed to be loaded?

Sorry if you've heard all this before but I just wanted  to cover the
basics first.
