A lot of things are safely possible :).

The stuff that's installed in the images is controlled by a bunch of scripts
in my pg-vm-images repository. For netbsd the relevant install is in

https://github.com/anarazel/pg-vm-images/blob/main/scripts/bsd/netbsd-prep-postgres.sh

As you can see we currently don't install packages from outside netbsd's
package repository. We could change that and install IPC::Run via cpan, but
imo it's obviously nicer - and more representative of real world setups - if
we just rely on OS/distro packages.

I don't know what would be required to get netbsd to upate their IPC::Run
package.
https://ftp.netbsd.org/pub/pkgsrc/current/pkgsrc/devel/p5-IPC-Run/index.html

If it were merged into netbsd, it'd be used for the CI images within a few
days, they are regenerated every few days [1] (or if a change the the image
sources is merged).
