Operating system:   Ubuntu
Description:        Shortcut for currently connected users
Details:

Dear developers, thank you for the perfect product!

I'd like to request one shortcut in psql terminal. That would simplify a lot
manual administrating of postgresql servers! The query I need always to
execute is

select * from pg_stat_activity ;

That would be nice to have something like "\cu" as a shortcut for this
query!!

Thank you!
