tablecmds.c: right.  Since 074c5cfbf

pg_dump.c: right.  Since b08dee24a

formatting.c: I don't see the problem.

        if (Np->sign != '-')
        ...
        else if (Np->sign != '+' && IS_PLUS(Np->Num))
        ...

You said that the "else" is never hit, but why ?
Maybe this part of the patch is wrong.
The only case for the first if not handled is sign == '-',
sign == '-' is handled by else.
So always the "else is true", because sign == '+' is
handled by the first if.
