Hmm, well it looks like he switched over to meson around 42 days ago
2024-02-01, looking at "calliphoridae" (skink has the extra
complication of valgrind, let's look at a more 'normal' animal
instead).  The first failure that looks like that on calliphoridae is
19 days ago 2024-02-23, and after that it's happening every 3 days,
sometimes in clusters.

But you're right that under meson the test takes a lot longer, I guess
due to increased concurrency:

287/287 postgresql:recovery / recovery/027_stream_regress
           OK              684.50s   6 subtests passed

With make we don't have an individual time per script, but for for all
of the recovery tests we had for example:

t/027_stream_regress.pl ............... ok
All tests successful.
