We have been trying to "push out" anything that is not fairly tightly
tied to the core backend, enough so that it's easier to maintain with
the backend than separately.  The PL languages are in a gray area, but
for the most part it seems better to treat them as part of the core for
maintenance purposes.  They tend to need fixed whenever we make any
changes to internal backend APIs.  (See for instance discussion just now
in pghackers with Thomas Hallgren --- if PL/Java had been part of the
core distro then he'd not now be playing catchup to make it work with
8.0 CVS tip...)
