DBLINK_CANCEL_QUERY(3)	PostgreSQL 9.6.3 Documentation	DBLINK_CANCEL_QUERY(3)

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');

PostgreSQL 9.6.3		     2017		DBLINK_CANCEL_QUERY(3)
