如何在node中捕获psql错误？

npm install pg

const { Client } = require('pg');

const client = new Client({
  user: 'your_username',
  host: 'your_host',
  database: 'your_database',
  password: 'your_password',
  port: 'your_port',
});

client.connect();

try {
  // 在这里执行psql语句或操作数据库的代码
} catch (error) {
  console.error('An error occurred:', error);
}

try {
  const result = await client.query('SELECT * FROM your_table');
  console.log(result.rows); // 处理查询结果
} catch (error) {
  console.error('An error occurred:', error);
}
