title: Permanently Set Postgresql Schema Path
body: <p>I need to set schema path in Postgres so that I don't every time specify schema dot table e.g. <code>schema2.table</code>. 
  Set schema path:</p>
  
  <pre><code>SET SCHEMA PATH a,b,c
  </code></pre>
  
  <p>only seems to work for one query session on mac, after I close query window the path variable sets itself back to default. </p>
  
  <p>How can I make it permanent?</p>
