"format" function documentation fix - Mailing list pgsql-docs

(Please CC me the reply, since I'm not subscribed to the list.)

Hi,

The last example from
http://www.postgresql.org/docs/9.3/static/functions-string.html#FUNCTIONS-STRING-FORMAT
- "examples using width fields and the - flag" seems to be incorrect,
see the attached patch.

Regards,
