The page suggests that the pattern modifiers (e.g. 'FM') only apply for Date/Time Format.
But at least FM can also be used for number types:
select to_char(1,'(99999)')
UNION ALL
select to_char(1,'(FM99999)')
-----------------------------
( 1)
(1)
Maybe it would be sufficient to just add FM into the table 9.24
( http://www.postgresql.org/docs/9.5/static/functions-formatting.html#FUNCTIONS-FORMATTING-NUMERIC-TAB... )

There are two separate tables (9-23, 9-25) showing which modifiers apply
for date/time and numeric cases, so I think it is fine as-is.
Mind you, the whole page is rather awkward. Perhaps it would benefit from
being thrown away and rewritten from scratch. I'm not volunteering though.
