If you had plpythonu installed before, that's a plausible thing
to do. (There was discussion some time ago about making the
python-2-to-3 transition less painful for users, but we failed
to come to any consensus about how; so manual fixes like this
are going to be needed for a lot of people.)
However, I don't understand how "drop extension plpythonu"
worked for you, given your previous query showing that
that extension wasn't installed.
