Something like that "-o" option would be nice.  But regardless of the solution, and given how simple & streamlined the install path/directions are, it seems to me to make sense to have some way of doing this that doesn't involve having to read through the setup script.  That could be

From looking at the script running:

postgresql-11-setup --help

will get you that information.

a simpler option, or it could just be a footnote on the install page, next to the initdb command, something like:

That would be nice, unfortunately I am not the person to get that done.
Your best bet on this would be to file an issue here:

https://yum.postgresql.org/contact.php

You will need a community account to do this.


Optionally initialize the database and enable automatic start:
   /usr/pgsql-11/bin/postgresql-11-setup initdb (*)
   systemctl enable postgresql-11
   systemctl start postgresql-11

(*) Some options for initializing the database can't be changed later (except by wiping out and reinitializing).  You can specify options by running export PGSETUP_INITDB_OPTIONS="<your options>" before running this command.  See <https://www.postgresql.org/docs/current/app-initdb.html> for options.
