The two collations will probably not behave identically, since PostgreSQL uses 
the
operating system collations instead of having ist own, and odds are that 
Microsoft's
collations and glibc's are slightly different.

I don't know if the impact will be large; maybe run a couple of tests to see if 
the
ordering is similar enough for your purposes.

I don't think that the actual encoing (UTF-8 or Windows-1252) has any impact on 
the ordering,
but I am not certain.

[GENERAL] Collations and codepages

2016-10-18 Thread Raimo Jormakka
Hi all,

In Windows 7, and using PostgreSQL 9.4.5, the collation gets set to
"English_United States.1252" when I select the "English, United States"
locale in the installer. In Linux, the collation is set to "en_US.UTF-8".
The encoding is set to UTF-8 in both instances.

Will these two instances behave identically in terms of collation logic?
And if not, is there something I can do about it? In general, what's the
impact of the codepage part of a collation to begin with?

Cheers,
Raimo
