Change language of system and error messages in PostgreSQL

Question

Is it possible to change the language of system messages from PostgreSQL?

In MSSQL for instance this is possible with the SQL statement SET LANGUAGE.

Answer 1

In my case (on Windows Server 2019) I managed to change language by creating a system environment variable "LC_MESSAGES" with value "English":

setx LC_MESSAGES English /m
