title: support for varchar[] array type in R2DBC Postgres Criteria
body: <p>I am trying to build a query similar to the below query using <strong>criteria</strong> query having varchar[] column in Postgres.</p>
  <pre class="lang-sql prettyprint-override"><code>SELECT * 
  FROM table_name 
  WHERE (arrays['value1','value2']::varchar[] &amp;&amp; column_name) 
  </code></pre>
  <p>But it appears that there is no out of the box support for <strong>varchar[]</strong> in R2dbcEntityTemplate.
  Is there any way to achieve this?</p>
