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)

All the cases you mention vary depending on what locale you're using.

Thanks for your reply!
I know pattern D and G depending on locale.
My default locale is zh_cn, but when I init DB using locale=en_us.utf8, I
still got the same result.
I haven't use other locales to test any more, maybe they will bring
different results.
Whatever, I think it's better to report here.
Maybe declaring the locale for the examples is better, if possible.
Regards!
