Question

我有一个类似JSONB的

<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->
  <title>Bootstrap 101 Template</title>

  <!-- Bootstrap -->
  <link href="css/bootstrap.min.css" rel="stylesheet">

  <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries -->
  <!-- WARNING: Respond.js doesn't work if you view the page via file:// -->
  <!--[if lt IE 9]>
      <script src="https://oss.maxcdn.com/html5shiv/3.7.3/html5shiv.min.js"></script>
      <script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"></script>
      <![endif]-->
</head>

<body>

  <!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
  <!-- Include all compiled plugins (below), or include individual files as needed -->
  <script src="js/bootstrap.min.js"></script>

  <div class="container">
    <div class="row">
      <div class="col-sm">
        One of three columns
      </div>
      <div class="col-sm">
        One of three columns
      </div>
      <div class="col-sm">
        One of three columns
      </div>
    </div>
  </div>
</body>

</html>

我想为标签添加唯一约束（所有这些标签都应该是uniq）。一种选择是Postgres中的函数，但我不喜欢它。

您还有其他想法吗？

在Postgres中通过JSONB数组创建唯一索引
