An alternate way might be to use semaphores, but I can't see how to do
that using the standard PGSemaphores implementation: it appears to
depend on cooperating processes inheriting a copy of the postmaster's
heap.
And since the POSIX semaphores default to unnamed ones, it appears
this idea is also a dead end unless my impressions are dead wrong...
