I'm resistant to assuming the postmaster is launched through pg_ctl.
systemd, for example, might well prefer not to do that, not to
mention all the troglodytes still using 1990s launch scripts.

A question that seems worth debating in this thread is how much
updating the process title is even worth nowadays.  It feels like
a hangover from before we had pg_stat_activity and other monitoring
support.  So I don't feel a huge need to support it on musl.
The previously-suggested patch to whitelist glibc and variants,
and otherwise fall back to PS_USE_NONE, seems like it might be
the appropriate amount of effort.
