psql: FATAL: role "vagrant" does not exist [duplicate]
You don't have vagrant user in postgres, and when you run psql, it tries to login as vagrant user (the same name as OS user). You may try something like:
psql -U postgres -h localhostto login as postgres user, with password specified in your Vagrantfile for postgresq user.
Then, you have several options:
Export
PGUSERandPGHOSTenvironment variables to set user and host (psqlwithout parameters will use these values). You may also want to use .pgpass file to avoid entering password on eachpsqlexecute.Modify Vagrantfile to create
vagrantuser in postgres with password
