我只想尝试为Rails应用程序设置PostgreSQL 9.5。首先我做了
$ createdb mydb
$ psql mydb
$ CREATE USER zip
$ grant all privileges on database mydb to zip;
$ CREATE ROLE zip superuser
$ GRANT ROOT TO zip
$ ALTER ROLE zip WITH LOGIN
$ CREATE ROLE zip superuser createdb login;
$ createdb zipzav_test
我用\q离开psql并运行
$ rake db:structure:load
psql: FATAL: Peer authentication failed for user "zip"
rake aborted!
failed to execute:
psql -q -f /home/faisal/Developer/Myapp/db/structure.sql mydb
请检查上面的输出是否有任何错误，并确保PATH中已安装psql且具有相应的权限。
