New Python vs. old PG on raccoon and jaguarundi

PostgreSQL 9.2 and later support Python 3.3 and Python 3.4; PostgreSQL 9.1 and
9.0 do not.  Buildfarm member raccoon upgraded from Python 2.7 to Python 3.3
for its 2013-08-18 run, and it has failed for REL9_1_STABLE and REL9_0_STABLE
ever since.  Please omit --with-python for those branches.  (Pointing to an
older Python is also an option.)  Incidentally, raccoon REL9_4_STABLE has
jammed for some time on a stale git lock file.  As best I recall, you can just
remove /usr/src/pgfarm/build/REL9_4_STABLE/pgsql and let the buildfarm client
re-clone it.

Buildfarm member jaguarundi, which has Python 3.4, activated --with-python for
REL9_1_STABLE as of its 2014-12-15 run.  Please remove --with-python or test
against an older Python.  It already omits --with-python for REL9_0_STABLE.

Thanks,
