An error message when running the "mix ecto.create" command

Hi!

I’m new here.

I was reading this page:

https://hexdocs.pm/phoenix/up_and_running.html

And then, when I tried to run it, I’ve got this message:

19:26:35.127 [error] GenServer pid<0.259.0> terminating
** (Postgrex.Error) FATAL 28P01 (invalid_password) password authentication failed for user “postgres”

Last message: nil
State: Postgrex.Protocol
** (Mix) The database for Hello.Repo couldn’t be created: killed

Does anybody know how can I fix?

Thank you for any help.

Alexandre.
