Hmmm... I doubt that this is directly related to the Windows issue, where the shared library simply doesn't exist in the standard installation.
Can anyone confirm whether the plpython2 omission from the Windows builds was intentional? If it is intentional, then a few simple changes would make it easier for users like me to figure out that it's missing, not just misconfigured:
* Make plpythonu point to plpython3u, rather than plpython2u, by default
* Omit plpython2u from the pg_pltemplate catalog, so that this:
CREATE LANGUAGE plpython2u
... would give a more helpful error message:
ERROR: unsupported language "plpython2u"
