收到错误 PG::ConnectionBad: FATAL: Peer authentication failed for user “job_portal”

Question

所以我一直在尝试使用 capistrano 将我的应用程序部署到生产环境，但出现了这个错误。 我已将我的 postgres 配置从 peer 更改为 md5。 我在 psql 中手动创建了 db job_portal 生产并将详细信息添加到 database.yml 文件中。 我尝试了很多东西，但似乎没有任何效果，我能得到一些帮助吗？

database.yml test: <<: *default database: job_portal_test host: localhost port: 5432 username: elrich_3 password: 12345 production: <<: *default database: job_portal_production host: localhost port: 5432 username: elr_4 password: 12345
