title: Postgres text array to hstore
body: <p>I have an array of even length, with comma delimited values (not necessarily homogeneous):</p>
  
  <pre><code>'{"a", 10000, "b", 20000}'
  </code></pre>
  
  <p>I would like to parse this postgres array into an hstore column, associating each odd entry (index 1,3,...) as a key, and each even entry (index 2,4,...) as value. Is this possible?</p>
