Hmm, there's only one actual question in that email, which is a
request for ideas about PL/pgsql vs. C.  I suspect you didn't get any
responses because the rest of the email seems to indicate that the
patch is not very mature at this point: for example, being able to
handle updates that move rows between partitions would seem to me to
be an essential feature for a project of this type, even though there
are many practical scenarios were it's unimportant.  Likewise, being
able to repartition sounds important.

With respect to the specific question about PL/pgsql vs C, I suspect
it's very unlikely that any patch of this type that relies on PL/pgsql
being loaded would be accepted into core.  However, it's possible that
a useful contrib module or pgfoundry project could be spawned on that
basis, and that might be a good place to start.

I think having a useful toolkit, or a core language feature, that
supports table partitioning would be awesome and would find very broad
application...  but it sounds like there is quite a bit of work left
to be done to get there.
