For precisely the reason stated upthread. That would mean creating and
deleting catalog entries for every transaction. Imagine a busy OLTP system
running hundreds of transactions per second trying to use a temporary table
for intermediate results. Mixing DDL and DML is just as bad an idea behind the
scenes as it is for users.

Global temp table can be created from template only when is used. It's
has not negative efect on app which doesn't use it. The benefit of
g.t.t. is simplifycation of stored procedures.
