pg_upgrade does have some code to handle plpython call handlers in
function.c:get_loadable_libraries();
* Systems that install plpython before 8.1 have
* plpython_call_handler() defined in the "public" schema, causing
* pg_dump to dump it. However that function still references
* "plpython" (no "2"), so it throws an error on restore. This code
* checks for the problem function, reports affected databases to the
* user and explains how to remove them. 8.1 git commit:
* e0dedd0559f005d60c69c9772163e69c204bac69
