True. There are good reasons to not run apache as root. There are also
perfectly valid reasons to run it as root, for such users who want to make
an informed decision.

My posts to the list are not going through. I am NOT advocating running
postmaster as root. I never was.

I don't think there is a non-condescending way to tell an administrator that
you think you know what is better for their operating environment than they do.

Everybody understands the pitfalls of running root daemons; I don't think there
is any more explanation required.

I definitely think there is benefit to starting an official "how to migrate"
document. There is already a lot of information up on the techdocs website
that someone pointed me to. I've found answers to all the questions that
I needed by looking around, but it might be nice to create a more coherent
explanation of the "mysql way" vs. the "postgresql way".
