Really struggling to get Postgres set up. I have installed it with home-brew (version 14). and installed the Postgres app through the website.
when I type the command 'psql' into my terminal it gives this error:
psql: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: FATAL: role "edac" does not exist
my server is running on port 5432.
any help will be appreciated.
A standard installation of Postgres has peer authentication enabled in pg_hba.conf. If you start psql without parameters it looks to connect with a DB role of the same name as the current OS user - obviously "edac" in your case.
Either you create such a role in the database (and grant desired privileges to it), or you connect with a different (existing) role. In a fresh installation, at least the database role "postgres" exists, which is a superuser.
Either you log in with username and password. Or simpler, connect as OS user "postgres" to allow peer authentication with the DB role of the same name. Like:
sudo -u postgres psql
Then you may want to create a DB role named "edac" (without superuser privileges):
CREATE ROLE edac;
Or, to just do that in one step with the shell command createuser:
sudo -u postgres createuser edac
