The last example from

the attached patch.

No, the example is correct. Referring to the documentation above that:

     If the width argument is negative, the result is left aligned (as
if the - flag had been specified) ...

This applies even if the "-" flag is also specified. So the last
example is meant to illustrate that 2 minuses don't make a plus here.

That's very unusual, IMO. This behavior follows some SQL standard or is it an invention of PostgreSQL?

Thanks,
