Involving the postmaster in this is entirely *not* reasonable. The
postmaster cannot do anything IPC-wise that the stats collector couldn't
do, and every additional function we load onto the postmaster is another
potential source of unrecoverable database-wide failures. The PM is
reliable only because it doesn't do much.
