DBLINK_CANCEL_QUERY(3) PostgreSQL 14.15 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');
