Re: postmaster shutdown - LWLockAcquire?

What are your client(s) doing to provoke this crash?  (If you don't
already know, try running the postmaster at -d2 to get logging of
queries.  Might want to turn on log_connections and log_pid too.)

I doubt that the template0 connection attempts are causing the crash;
at least that doesn't seem to cause any problem here.

The LWLockAcquire failure suggests that some code path is trying to
invoke LWLockAcquire before locking support has been set up in a new
backend.  But I have no idea where that could be, if it's being seen
by you and not anyone else.

I don't suppose you'd consider "run a real OS" as helpful advice ;-)
