Re: How to find correct locale name for CREATEDATABASE

Postgres requires those suffixes in locale names.
They must me exactly UTF8 or UTF-8 or 1257 .
If those are missing, or even if - sign is missed in UTF-8, error occurs on

create database test lc_collate '...'

So all those invariants must be used in probing.

I need locale mostly for ILIKE and ORDER BY to work properly.

Yes.

No

No

set lc_ctype to 'et_EE'

or to other value returns

parameter "lc_ctype" cannot be changed

I need to know locale name to set locale.
Is there some simple command which can used to test for locale existence for
create database command ?
