I saw your message about that after sending mine. Yes, that'd be
a cool way of displaying the relationship. But the main thing to
remember is that it'd only be correct at steady-state when nothing
is being changed. If we tried to guarantee the mapping was correct
100% of the time, we'd be back to square one. Of course, that
makes the whole thing somewhat less useful for debugging purposes,
since Murphy's Law says that the times you really need to know
what's what are just when the system crashed in the middle of
a table rename ;-)
