missing perl test modules in postgresqlXX-devel ?

Hi,

I noticed the perl test modules from PostgreSQL source tree, eg.
PostgresNode, are not installed with package "postgresqlXX-devel". Only
pg_regress is installed.

Looking at the web, I can find old memories [1] where postgresql12-devel
installed them in /usr/pgsql-12/lib/pgxs/src/test/perl/

Comparing with Debian packages, they install both pg_regress and perl modules
with the client package under:

  $(pg_config --pkglibdir)/pgxs/src/test/perl/
  $(pg_config --pkglibdir)/pgxs/src/test/regress

Is it on purpose?

Regards,
