Not directly, but you could try something like

perform * from pg_class where
relname = 'mytable' and pg_table_is_visible(oid);
if not found then ... -- create the table

The visibility test would not succeed for temp tables belonging to other
backends. (If 'mytable' is also used as the name of a regular table
then this isn't quite good enough, but I think just avoiding such a name
collision is easier than extending the check to reject non-temp tables.)
