title: Save few values to the row in Postgres
body: <p>Is it possible to save few values to the row. For example, I have 2 tables:
  For Participants:</p>
  <pre><code>CREATE TABLE participants (
    id PRIMARY KEY,
    uuid BIGINT UNIQUE
  );
  </code></pre>
  <p>And for Voters:</p>
  <pre><code>CREATE TABLE voters (
    id PRIMARY KEY,
    uuid BIGINT UNIQUE,
    participants -&gt; here I want to save all available uuid from participants table
  );
  </code></pre>
  <p>I want to get array of participants uuid after executing <code> SELECT participants FROM voters WHERE uuid='someuuid';</code></p>
