OK, based on the lack of excitement in doing anything more invasive, I
have applied the pg_upgrade fix to PG 9.2 for the plpython helper
function appearing in the public schema and referencing an old shared
library.

Should this be back-patched?  (Problem first reported in PG 9.1 due to
the removal of a backward-compatibility symlink.)  I am not sure we have
had enough problem reports to warrant it (3 reports).

(Should bug discussions stay on the bugs list?  I did for this bug.)
