Yeah, that sounds exactly what I was thinking.

Now, what is the worst that can happen if we rename a table under SUE
and somebody else is using the table concurrently?  Is there any way to
cause a backend crash or something like that?  As far as I can see,
because we grab a fresh catalog snapshot for each query, you can't cause
anything worse than reading from a different table.  I do lack
imagination for creating attacks, though.

So my inclination would be to apply this to master only.
