I don't know the UUID thing but what may make a difference would
be a little performance penalty (inserting a value instead of
letting postgres handle the SERIAL its way). But it should be
minimal, I think.
Also, let's not forget to document the importance of creating an
index on the UUID column, if we're going to select by UUID, which
I guess will be the case.
the code is in gwlib/gw_uuid.[ch].
Alex did a lot for research at the time he introduced the UUID implementation as
a message ID for the transport layers in Kannel. And he did a great work to
explain the necessary parts at that time. From my perspective I trust his
research and words, even while I never tried to "understand" the UUID heuristics
in detail by the code. (I admit I reviewed some other projects and references
for UUID and have been simply convinced.)
