Yes, you can.

If what you mean here is a c-style typedef no not really but you can use
inheritance.
If what you mean is another name by which to refer to a table or row then
the answer depend complete upon the context. In rules tables are already
referenced as new, old, current. In pl/pgsql you can create references
until your hearts content.

PostgreSQL isn't fully SQL3 compliant, but it's getting there.
