Hello, Please note: I'm talking about the user and group "postgres" in the Linux OS and not in the PostgreSQL server. We're compiling PostgreSQL from source (actually 14.1) and distribute that to our customers. They're asked to setup user and group "postgres" before creating the cluster. As nowadays there are a lot of setup such things in bigger installations, like LDAP or AD, etc. I'd like to know how other installations for Linux deal with this?
