title: Set formula for Computed column of PostgreSQL table in Entity Framework Core
body: <p>I have a simple model with Id and a json property and a computed column which is value of <strong>'tile'</strong> key in the json column</p>
  <pre><code>public class Book 
  {
      public int Id { get; set; }
  
      [Column(TypeName=&quot;jsonb&quot;)]
      public string JsonInfo { get; set; }
  
      [DatabaseGenerated(DatabaseGeneratedOption.Computed)]
      public string Title { get; set; }
  }
  </code></pre>
  <p>in the configuration I set the way which the value of <code>Title</code> is caculated:</p>
  <pre><code>    builder.Property(t =&gt; t.Title).HasComputedColumnSql(&quot;(\&quot;JsonInfo\&quot;-&gt;&gt;''title'')&quot;, stored:true).HasColumnType(&quot;varchar(150)&quot;);
  </code></pre>
  <p>the migration is build without problem, but unfortunately the database update ends with an error:</p>
  <p><code>42601: syntax error at or near &quot;title&quot;</code></p>
  <p>The problem is within the <code>&quot;(\&quot;JsonInfo\&quot;-&gt;&gt;''title'')&quot;</code> that how the <code>title</code> is escaped. How can i fix it?</p>
  <p>Just to mention, i use latest version of PostgreSQL</p>
