It looks like someone is holding a critical LWLock --- hard to tell if
it's the BufMgrLock or a per-buffer lock for a system index's metapage,
but must be one or the other. Try backtracing the processes that
*aren't* hung in this particular way. I'm not sure you'll be able to
learn anything much given that the build doesn't have debug info, but
you might as well try.
