Tiny typo in the 8.4 docs

Hello,

I was just wading through the new PG 8.4.0 documentation and found a
tiny typo in:

-------- begin sample -------------

9.16.3. NULLIF
[...]

SELECT NULLIF(value, '(none)') ...
If value1 is (none), return a null, otherwise return value1.

-------- end sample -------------

Either use 'value1' in the SELECT-clause too, or 'value' in the
explanation.

Nothing serious, but maybe for the sake of perfection, you may want to fix
it in next version. Thanks.

Regards,
vmk
