title: Set deafult schema while querying in pgAdmin 4 with query tool
body: <p>Whenever i have to execute sql commands in <code>pgAdmin 4</code> i have to append <code>schema_name</code> with tables.
  Eg :- </p>
  
  <pre><code>SELECT * FROM my_schema.users //where myschema is schema name
  ORDER BY id ASC  
  </code></pre>
  
  <p>Is there any way to execute sql commands in <code>pgAdmin 4</code> without schema name, by setting a default schema in advance.</p>
  
  <p>Some thing like this</p>
  
  <pre><code>SELECT * FROM programme
  ORDER BY id ASC 
  </code></pre>
  
  <p>- without specifying schema name with table. </p>
  
  <p>Is there a way to set default schema in  <code>pgAdmin 4</code> for querying in sql tool?</p>
