It seems to me that pgfincore has the smarts we need to know about that,
and that Cédric has code and refenrences for making it work on all
platforms we care about (linux, bsd, windows for starters).

Not really. I'm convinced, and not only for e_c_s, that
autoconfiguration is within the realm of possibility.
Hey, if you can do it, my hat's off to you.
In any case, as eavesdroppers can infer a cryptographic key by timing
operations or measuring power consumption, I'm pretty sure

This is a pretty common gotcha: user sets shared_buffers but misses
the esoteric but important effective_cache_size. ISTM

All,
Well, the problem of find out the box's physical RAM is doubtless
solvable if we're willing to put enough sweat and tears into it, but
I'm dubious that it's worth the trouble. The harder part is how to know
if the box is supposed to be dedicated to the database. Bear in mind
that the
