Yep, the fact the switch defaults to nothing can be a problem. Some
day, I was going to look at all the switch defaults to make sure
skipping it is really the proper thing to do, rather than elog out.

Actually, it does handle unions of views, but not views of unions.
Informix doesn't support it either, and I don't know what the other
dbms's do, but I think I am going to find out soon from someone. :-)
I will move it to the TODO list.
