DBLINK_CANCEL_QUERY(3)            PostgreSQL 12.3 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');
