How to do pg_dump + pg_restore within Perl script?

I would like to replicate the following Unix pipe within a Perl script,
perhaps using DBD::Pg:

% pg_dump -Z9 -Fc -U <DB_USER> <FROM_DB> | pg_restore -v -d <TO_DB> -p
<SSH_TUNNEL_PORT> -h localhost -U <DB_USER>

Of course, I can try to use Perl's system, and the like, to run this pipe
verbatim, but I this as a last-resort approach.

Is there a more direct way?

Thanks!
