  <para>
   <function>pg_send_execute</function> executes a previously prepared
   named query on the <parameter>connection</parameter>, with the
   specified parameters.  Unlike <function>pg_execute</function>, script execution 
   is not blocked while the query is executing.
  </para>
  <para>
   <function>pg_send_execute</function> returns a query result resource if
   the named prepared query could be executed with the given parameters.  
   It returns &false; on failure or if connection is not a valid connection.
   It is identical to <function>pg_send_query_params</function>
   except that it takes the name of a previously prepared query instead
   of an actual query.
