Hello,

I am using PostgreSQL 18.1 on a Windows system.
I need to move that database to a Linux system of the same version number.

Windows system use locales name as tr-TR (this is UTF-8 locale)
Linux system use locale name as tr_TR.UTF-8

My cluster backup gives error at restore (I think because of that locale naming difference) as below

psql:/db.dump:133: ERROR:  invalid LC_COLLATE locale name: "tr-TR"

I should have added to previous post what does, in psql, the below return:

\l <database_name>


And a bunch of other errors below.

What can I do to complete this migration?

Thanks & Regards,
Ertan
