title: NamedParameterJdbcTemplate and JSON in Postgres
body: <p>Is it possible to insert json into a postgresql json column using the <code>NamedParameterJDBCTemplate</code> class in SpringFramework and I am getting a <code>PSQLException: No hstore extension installed.</code> From this I gather that the <code>NamedParameterJDBCTemplate</code>is trying to store the value as hstore. </p>
  
  <p>Is there a way I can tell the <code>NamedParameterJDBCTemplate</code> to insert the value into the query as json? </p>
  
  <p>The value is stored in java as a <code>Map&lt;String, String&gt;</code></p>
