CREATE OR REPLACE is indeed much more complicated. In fact, for

This may in fact be an appropriate way to handle the case for tables,
given the complexity of their definitions.
Patch attached.
I had an initial look at Robert's patch. Patch applies cleanly,
documentation and regression tests included, everything works as expected.
When looking at the functionality there's one thing that strikes me a
little:
be...@localhost:bernd #*= CREATE TABLE IF NOT EXISTS foo(id int);
ERROR: duplicate key value violates unique constraint
"pg_type_typname_nsp_index"
DETAIL: Key (typname, typnamespace)=(foo, 2200) already exists.
This is what you get from concurrent CINE commands. The typname thingie
might be confusing by unexperienced users, but i think its hard to do
anything about it ?
