I think fixing single user mode to work halfway reasonable is enough
justification for the feature. Having to deal with that when solving
critical issues is just embarassing.

I think the patch as proposed actually reduces maintenance overhead
since we don't have to deal with the strange separate codepaths for
single user mode.

But: I very, very much agree with the other concerns around this. This
should be a patch to fix single user mode, not one to make postgres into
a single process database. It's not, and trying to make it by using
single user mode for it will start to hinder development of normal
postgres because we suddenly need to be concerned about performance and
features in situations where we previously weren't.
