Well, in most cases, if you don't know, you do BEGIN ... COMMIT, but in
the case of VACUUM/TRUNCATE, you can't do that, so you need some smarts.

It is a contrived example.  I am just throwing it out for illumination.
I often throw out scenarios at the edges to see if it strikes anyone as
a problem.  When it doesn't, we can move ahead.
