Subject: Choosing default collation/ctype

Hi, ALL,
In the CREATE DATABASE statement I can use encoding/collation/ctype.

I can retrieve the encoding list with:

[code]
SELECT pg_encoding_to_char( conforencoding ) AS name FROM pg_conversion
[/code]

And then I can get a list of collations/ctypes with:

[code]
SELECT collname, collencoding, collprovider collctype FROM pg_collation
[/code]

And then add a logic in my UI to switch collations/ctypes based on encoding.

However, what I wonder is:

Is there a way to select a default collation/ctype for a specific encoding?

Or maybe I'm overthinking it and I should let the user choose and if
nothing - just keep those 2 as "Default" and let the server pick it
up. However it will be weird, especially from me as a user POV.

Please advise.

Thank you.
