right, I had one function relaying on plpython2u so I changed it... but the again pg_upgrade claims error with python:

Log into each database and try to do that, and you will get something like this if you still have functions using it: postgres=# DROP LANGUAGE plpython2u; ERROR: cannot drop language plpython2u because other objects depend on it DETAIL: function testfunc() depends on language plpython2u HINT: Use DROP ... CASCADE to drop the dependent objects too. If you have no functions using it, it will just go away, and once you have dropped it in both databases you should be good to go. And of course, if there are functions depending on it, you should rebuild those on plpython3u before you drop plpython2u (or drop the functions if they're not in use). -- Magnus Hagander Me: https://www.hagander.net/ Work: https://www.redpill-linpro.com/ -- Pozdrawiam Marcin Giedz Wiceprezes Zarządu ARISE Sp. z o.o. mob. +48 606 673 977 mail: marcin.gi...@arise.pl Al.
