See where it says [ ( *column_name* [, ...] ) ]? The square brackets mean "optional", and the ",..." means repeat as needed. The fact "column_name" is italics tell you it's some kind of variable text you should replace, and later on in the page explains what goes there. So it's telling you that you can use a comma separated list of column names from the destination table. PostgreSQL has some of the best documentation of any software I've ever seen. Don't hesitate to check it often when working.
