为什么我的超级用户无法在psql中进行身份验证?

Knex:warning - Pool2 - Error: Pool was destroyed Knex:Error Pool2 - error: password authentication failed for user <username> Unhandled rejection Error: Pool was destroyed

// Update with your config settings.

module.exports = {

  testing: {
    client: 'postgresql',
    connection: {
      database: 'learnco_blog_test'
    },
    pool: {
      min:0,
      max: 10
    },
    migrations: {
      tableName: 'knex_migrations'
    }
  },

  development: {
    client: 'postgresql',
    connection: {
      database: 'learnco_blog',
    },
    pool: {
      min: 0,
      max: 10
    },
    migrations: {
      tableName: 'knex_migrations'
    }
  },

}; 

我将pg_hba.conf文件更改为“信任”IPV4和IPV6上的所有连接,我认为这可以解决问题,但它一直存在。你知道还有什么原因吗?可能是knexfile里的什么东西吗?我使用的是psql 10.4、Ubuntu 16.04、knex 0.10.0和pg 4.5.5。谢谢
