Is there an easy way to get a list of held lwlocks out of gdb attached to a core dump (or for that matter attached to a live process)?

I can try manually walking the internal data structure, but I am hoping for something analogous to the way you get memory contexts:

(gdb) p MemoryContextStats(TopMemoryContext)

Cheers,

Jeff
