The body of a function is just text, so what you put in is what you get out.

The view definition is presumably in the form of a parse-tree or some
such, so what you get back is a human-readable form of that rather than
what you type at the keyboard.

It's the same with pg_dump's interpretation of your table definitions -
you don't get the formatting nor even the "shape" of your definition I'm
afraid.

What are you trying to do that requires the original definition?
