Adrian and Bèrto,
Thank you very much for quick and excellent replies. Locale names are
different in every Linux distro.
Postgresql does not provide any way to retrieve them (ssh access is reqired
to retireve them using locale -a)
Thus suggection using hard coded locale names is not possible.
How to force server to use et_EE.UTF-8 as default locale without hard coding
it into application?
How to force command
CREATE DATABASE <yourdbname> TEMPLATE = template0
to use et_EE.UTF-8 locale by default ?
Andrus.
