1 & 3 are standard CLI commands that can be scripted as well as anything
else you do on your system. (3 would be scripted already so that pg
starts with the system)

2 is a simple editing of a file that gets performed once after step 1.

You would only do steps 1-3 once on a system (maybe a few more if you
are repeating it as a learning experience)

cratedb on the other hand may be something that gets run every time a
new user gets added to your server.

If you are looking to automate step 4 then you bypass the password
prompt with a trust entry that is only for the machine or user that will
perform the operation. The other option is using a .pgpass file.

If you are at a point where you want to automate setting up a large
number of new systems and you don't know enough about *nix systems to
create these scripts yourself then you should take a few steps back and
learn more about *nix sysadmin before you move on.
