We could have a stack to store parameters before temporary changes, for instance if you want to do one csv export and come back to normal without assuming what "normal" values were.
I think it might be a good idea to decide whether psql is to be a programming environment, or just a command shell.
If it is to be a programming environment, we should either adopt an existing language or strike a committee of programming language experts to design a new one.
If it is to be a command shell, new features should be evaluated in part on whether they move psql significantly closer to being a programming language and rejected if they do.
