This is listed on the open items list.
I haven't ever heard anyone propose to redefine CREATE LOCAL TEMP
TABLE to mean anything different than CREATE TEMP TABLE, so I'm
disinclined to warn about that.
I would be more open to warning people about CREATE GLOBAL TEMP TABLE
- frankly, it's pretty wonky that we allow that but treat GLOBAL as a
noise word in this first place. But I'm a little disinclined to have
the message speculate about what might happen in future versions of
PostgreSQL. Such predictions don't have a very good track record of
being accurate.
