I know that feeling.

"""
Any registered shmem_startup_hook will be executed shortly after each
backend attaches to shared memory.
"""
IMO the word "each" here can give the wrong impression as if there are
certain guarantees about synchronization between backends. Maybe we
should change this to simply "... will be executed shortly after
[the?] backend attaches..."
"""
should ensure that only one process allocates a new tranche_id
(LWLockNewTrancheId) and initializes each new LWLock
(LWLockInitialize).
"""
Personally I think that reminding the corresponding function name here
is redundant and complicates reading just a bit. But maybe it's just
me.
Except for these nitpicks the patch looks good.
