Just to notice Mandriva still provide postgresql setup by default with a trust
authentication and only local connections are allow. In fact the initdb is
run at first 'service postgresql start', we assume the sys admin will setup
it.
But If you (postgresql team) have any other preference (this can help for new
user to have the software setup like all documentation said), just warn me, I
have no problem for such change (I am the maintainer of postgresql for
mandriva, so I have the control for this).

ident is a really old protocol, it is nice to avoid to user to enter their
password for locales connections, but it is completly untrusted from a remote
computer. Most of admin will simply said you running identd is only a way to
have security issues, and it is often filtered, hopefully nobody filter it
loopback interface :)

Nothing really except I agree (as user and as packager), and again, if you
have a preference about the default method distribution should provide, just
said, I'll done it for mandriva in my case.
