Mix setup on macOS leads to "role "postgres" does not exist"

[raffaelschneider]

Setup

• macOS Ventura 13.4
• Elixir 1.14.4, Erlang/OTP 25 (erts-13.2.2)
• cmark-gfm (0.29.0.gfm.13) compiled and installed

Issue
I tried to setup the project as described with $ mix setup and get the following log output.

Log output

Hi @raffaelschneider you can edit the database configuration to reflect your environment or you can create that user if it's missing:

CREATE USER postgres WITH PASSWORD 'postgres';
