There was a patch last year to do something like that:
https://www.postgresql.org/message-id/56BDDC20.9020506@postgrespro.ru
While Test::More is part of any standard installation, IPC::Run is
not. FWIW, I still think that this is worth checking for. That's way
better than having the TAP tests explode with a weird fatal failure
where one needs to dig into the logs just to find out that the module
is missing.

Attached is an updated patch, with credit mainly going to Eugene
Kazakov. I have run autoconf myself, I know that usually committers do
that... Hope you don't mind.
