I'm attempting to install postgresql 10 for the first time and need to run the initdb setup. Unfortunately, this fails and returns an error from the nologin shell.
server# /usr/pgsql-10/bin/postgresql-10-setup initdb
Initializing database ...
failed, see /var/lib/pgsql/10/initdb.log
server# cat /var/lib/pgsql/10/initdb.log
This account is currently not available.
I strace'd the command and verified the su commands are probably what's causing this and it seems the default setting for the postgres user is /sbin/nologin. In various examples I've seen, there is no mention of this being a possible issue. How would this work on any other system by default? I feel that temporarily modifying the login shell would work but I want to understand this issue better more specifically from the application's end.
