The current definition of Hot Standby is that it's a *read only*
behavior.  Not read mostly.  What you are proposing is a rather
fundamental change in the behavior of HS, and it doesn't seem to me
that it should be on the head of anybody else to make it work.

IOW: I agree with Robert that this is not an essential part of global
temp tables.  If it happens to fall out that it works like that, great,
but it isn't a requirement.
