I'd agree that pgsql should REQUIRE LOGIN, but I think the reason is
subtilly different. In my mind the key with LOGIN is that the system
is ready security wise to allow users to interact with the machine via
methods other than the administrative console. This should mean the
secure level is elevated and any other security bootstrapping is done.
IIRC this is actually not the case and should be fixed. Running as an
unprivleged user isn't usable as a differentiating feature. For example
dhclient runs in part as an unpriveleged user.

There are a couple problems with "REQUIRE postgresql" in general:
- There's no requirement that you run a database on the machine the
application is on. (This is why ports depend on the -client not the
- Several ports will work out of the box with either postgres or mysql
so depending one or the other is wrong. As is depending on both.
I think the right thing is create a stub DATABASE provider that mysql
and postgres can be BEFORE. Ports that want a database can just depend
on that. It will insure that ordering is correct if the server is local
without causing problems if it isn't or requiring script modifications
for ports that can use more than one database from the same package.
