title: Easily output the hstore format of a table row
body: <p>Is there a better way to get a row of a table into hstore format than going</p>
  
  <pre><code>SELECT hstore(ARRAY['col1','col2','col3'], ARRAY[col1::text, col2::text, col3::text]) FROM tbl;
  </code></pre>
  
  <p>It works, but I figure there has to be a better way than typing out each column. hstore takes a record type for input, but I couldn't figure out how to feed the single-row producing query into the function and make it happy. Postgres version 9.0.4.</p>
