var pg = require('pg');
var pgConString = "postgres://icm:test@192.168.3.20/icm";
var client = new pg.Client(pgConString);
// PG update
        pg.connect(pgConString, (err, client, done) => {
            // Handle connection errors
            if(err) {
                  done();
                  console.log(err);
                  //return res.status(500).json({success: false, data: err});
            }
            // SQL Query > Update Data
            var sql_update = "UPDATE becctv SET becamonoff = '1' WHERE mid = '"
                + mid + "' AND bescode = '" + scode + "' AND becamid = '"
                + camid + "'";
            console.log('sql_update 000 = [ ' + sql_update + ' ]');

            const query = client.query(sql_update);

            // After all data is returned, close connection and return results
            query.on('end', function() {
              done();
              //return res.json(results);
            });
        });

為什么會發生此錯誤？

pg安裝錯誤？

謝謝。

pg.connect在pg.connect被棄用，在v7.0.0中被刪除。 您仍然可以執行client.connect ，但是推薦的方法是pool.connect-請參閱官方文檔。
