Threes errors of to_char Examples

Hi all!

I found three errors in postgresql9.4.1document, they are about to_char
examples.

Maybe other version of document also have those errors. Please Check and
modify~

In Chapter 9. Functions and Operators of
<http://www.postgresql.org/docs/9.4/interactive/index.html> PostgreSQL 9.4.1
Documentation, I found this:

expression

result

to_char(148.5, '999D999')

' 148,500'

to_char(3148.5, '9G999D999')

' 3 148,500'

to_char(485, 'PL999')

'+485'

But, in fact their result are as follow:

postgres=# select to_char(148.5,'999D999');

to_char

----------

148.500

(1 行记录)

postgres=# select to_char(3148.5,'9G999D999');

to_char

------------

3,148.500

(1 行记录)
