Request new version to support "on commit drop" for create temp table ... as select ?

Good morning,

I googled to find that "on commit drop" does not support:

(a) create temp table as select * from table1 where 1<>2;
http://archives.postgresql.org/pgsql-sql/2005-09/msg00153.php

If table1 has complex table structure, grammar(a) will save lots of
codes - col1 varchar(1), col2, ..... colN

I just wonder would the new version support "on commit drop" for select?

Thanks a lot!
