Well, that just means that it's not an *obvious* security risk.

I still like the idea of providing something comparable to
MemoryContextStats, rather than creating a SQL interface.  The problem
with a SQL interface is you can't interrogate it unless (1) you are not
already inside a query and (2) the client is interactive and under your
control.  Something you can call easily from gdb is likely to be much
more useful in practice.
