 NAME
      dblink_cancel_query - cancels any active query on the named connection

 SYNOPSIS
      dblink_cancel_query(text connname) returns text

 DESCRIPTION
      dblink_cancel_query attempts to cancel any query that is in progress
      on the named connection. Note that this is not certain to succeed
      (since, for example, the remote query might already have finished). A
      cancel request simply improves the odds that the query will fail soon.
      You must still complete the normal query protocol, for example by
      calling dblink_get_result.

 ARGUMENTS
      connname
          Name of the connection to use.

 RETURN VALUE
      Returns OK if the cancel request has been sent, or the text of an
      error message on failure.

 EXAMPLES
          SELECT dblink_cancel_query('dtest1');
