Answering to myself: I was using pgAdmin to create the database, and this tool does not show much collations.
I could create my database from the command line: createdb --username=postgres --port=5436 --template=template0 --encoding=latin9 --locale=English_US.28605 test2 Stop me if I am wrong.

Hi! On my Windows 10 with PostgreSQL 15, I try to create a database with LATIN9 encoding (for testing purpose), but I have only the choice to select the C, POSIX and English_United States.1252 collations... C and POSIX are compatible with LATIN9, but SQL functions like UPPER() fail. English_United States.1252 is not compatible with LATIN9. I do not want to use WIN1252 encoding, I must use LATIN9 because it's for QA tests and my programs need LATIN9 (comes from Linux) Do I have to create/install more locales on this PostgreSQL 15 / Windows installation? I wonder... I while ago with PostgreSQL 13 I have created a DB with LATIN9 on this machine. I must be missing something, can't remember how I did that. Can someone point me to the doc page where I can find related info? Thanks! Seb
