Обсуждение: Change in behaviour of ORDER BY clause in PG7.3

Since upgrading to 7.3 I've noticed that the ORDER BY clause seems to 
ignore leading spaces/punctuation for eg we have a simple table with 6 
rows containing:

'a'
'b'
'c'
'd'
' bill'
'-bill'

SELECT * FROM table ORDER BY 1;

gives:

a
bbill
-bill
c
d

which is different from previous versions and different to MySQL and SQL 
Server. Is this a bug, or can you turn this behaviour off? It's breaking a 
lot of our applications!

You need to set the right locale.  You appear to expect the "C" locale, so
you need to tell initdb about it.

       Could you clarify which vendor's SQL Server you're referring to?  Or do 
you mean a subset of MySQL or PostgreSQL?
