Re: BUG #16843: pg_upgrade from 12.5 to 13.1 with extension plperlu failed

Hello, (third trial)

to clearify,

- plperl package is already installed (see below).

- command 'CREATE OR REPLACE PROCEDURAL LANGUAGE "plperlu";' doesn't create a

language object, but just an extension object (see below)

Output from failed database upgrade:
