Hello,  
I launched an update after probably a year, which led to the upgrade from pg 13 to 15.

I’m trying to run the given command with my own LC\_LANG but it’s not working, I get `FATAL: data directory “/shared/postgres_data” does not exist`. And indeed it doesn’t exist… Does anyone have an idea?
