Well in the image they need to make the plperl language available. If
they are building from source then it needs to be compiled with:

https://www.postgresql.org/docs/11/install-procedure.html
--with-perl

Build the PL/Perl server-side language.

If they are using packages then they will need to include the
appropriate package.
