Once again thanks very much for your time.

That basically makes it even. In the sense, that from this point of view 
there is no preference.

I am paying attention to the fact that the author of PAF replies to 
beginners question. Beginner at least in this regard.

Other than that, at least the copyright notice for the pgsql ra is from 
2012. Wether this is actually an indicates for any evolution I do not 
know, as I have not done any further digging.
It still should work, that's the message I am taking away from this 
thread, with more or less feature parity, so we'll give it a try as well.

Well, if we manage to get it up and running by help of documentation, 
and some trial and error, we may not really need to read the agents 
anyway. In fact, that is, what we hope. It would just be a fallback 
since everyone here pitied either documentation

For evaluation we actually prefer going completely on foot and not use 
any automation magic. I am a bit oldfashioned and rather learn by doing 
wrong than by reading yaml. What in turn prevents any further career, 
but that is an entirely different story.

Thanks again, very highly appreciated!
