yes, but again, plpython3 would depend on having python-libs for python
3.x, which EL5/6 do not provide. the plpython provided by
yum.postgresql.org has dependency on...

$ yum deplist postgresql91-plpython
postgresql91-plpython.x86_64 9.1.5-3PGDG.rhel6
.....
dependency: libpython2.6.so.1.0()(64bit)
provider: python-libs.x86_64 2.6.6-29.el6_2.2
