Hi,

5.8.3 is from 2004-Jan-14, that's impressive :). I don't see any benefit in
setting up a buildfarm animal running that old a version.
For the meson stuff it'd suffice to set 5.9.3. as the minimum version for
plperl (or I could try to work around it). However, supporting a perl version
from 2006-Jan-28 doesn't strike me as particularly useful either.
Relevent somewhat recent discussion / work:

I looked at which buildfarm animals currently use 5.14 (mentioned by John),
and it's frogfish, snapper and skate. The latter two do build with plperl.
I started a query on the buildfarm machine to collect the perl versions, but
it's just awfully slow...
Greetings,
Andres Freund
