Well, mainly that it's making our regression tests fail, which suggests
behavioral instability that could be important for production.
Aside from the specific case you diagnosed, it's clear from buildfarm
results that the five-second timeout elsewhere in
test_postmaster_connection has got funny behavior under load; there are
way too many cases where pg_ctl gives up after exactly that long, with
no useful information printed. The draft patch I posted gets rid of that
behavior ...
