Problem about pgsql's column alias

Hello, everybody

I found that in postgresql, we can only use "select login_name as name from
users;" to get an alias "name" for column "login_name", but in most other
databases we can omit the "as", that is "select login_name name from users;".

Now I will convert a lot of program from oracle to postgresql, there're so
many place to be correct from "AAA BBB" to "AAA as BBB", can anybody give me
a good method to do that? Or, if the next version of postgresql will have the
same feature as other databases?

Thanks a lot,
Yours,
