title: Inner join on one PostgreSQL database table and another one is normal array
body: <p>I am new to PostgreSQL.
  Can you please tell me why the below query is not working.</p>
  <pre><code> Select * 
   from custom_test as dbtable 
     inner join aLocalArray as localtable on dbtable.id = localtable.id
  </code></pre>
  <p>Here custom_test is database table in PostgreSQL. aLocalArray is an array which is prepared by me.</p>
