Hi all, trying to performe upgrade from 12 to 13 installed from Centos8 repo 
gives such error: 

cat loadable_libraries.txt 
could not load library "$libdir/plpython2": ERROR: could not access file 
"$libdir/plpython2": No such file or directory 

digging around: 
1. 
drop extension plpythonu; 
ERROR: extension "plpythonu" does not exist 

2. 
postgres=# select * from pg_pltemplate ;

5. 

postgres=# SELECT oid::regprocedure 
postgres-# FROM pg_catalog.pg_proc

Question: where is plpython2 comming from during pg_upgrade? Is this pg_upgrade 
bug or something else? 


Thx 
Marcin
