node-postgres：[error]該套接字已被對方終止

Question

我使用node-protgres來操作我的nodejs應用程序中的數據庫。

我做了什麼：

const { Pool, Client } = require('pg') 
var dbconnect = { 
    user: 'xxxxx', 
    database: 'xxxxx', 
    password: 'xxxxx', 
    host: 'xxxxx.yyyyy.zzzzz.eu-west-1.rds.amazonaws.com', 
    port: 0000, 
    max: 20, // max number of clients in the pool 
    idleTimeoutMillis: 30000, 
    connectionTimeoutMillis: 2000 
}; 
const pool = new Pool(dbconnect); 
pool.on('error', function (err, client) { 
    console.error('idle client error', err.message, err.stack) 
}); 

function listOfPets(req, res) { 

pool.connect(function (err, client, done) { 
     if (err) { 
      return console.error('error fetching client from pool', err); 
     } 

     var sql = 
      "SELECT * FROM pets" 
     client.query(sql, function (err, result) { 

       done(); 

       if (err) { 
        return console.error('error running query', err); 
       } 

       ... //Handle the result 

      }); 
    }); 

} 

功能工作正常，但是服務器繼續向我發送錯誤報告OK嚴重。我檢查了日誌：

idle client error This socket has been ended by the other party Error: This socket has been ended by the other party at Socket.writeAfterFIN [as write] (net.js:291:12) at Connection.end (/var/app/current/node_modules/pg/lib/connection.js:313:22) at global.Promise (/var/app/current/node_modules/pg/lib/client.js:410:23) at Client.end (/var/app/current/node_modules/pg/lib/client.js:409:12) at Pool._remove (/var/app/current/node_modules/pg-pool/index.js:135:12) at Timeout.setTimeout (/var/app/current/node_modules/pg-pool/index.js:38:12) at ontimeout (timers.js:365:14) at tryOnTimeout (timers.js:237:5) at Timer.listOnTimeout (timers.js:207:5)

我覺得問題來自'done（）'不起作用或被放在錯誤的地方。

任何建議表示讚賞。
