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.
