There must not be an async query already in progress on the connection. After successfully dispatching an async query, completion status can be checked with dblink_is_busy, and the results are ultimately collected with dblink_get_result. It is also possible to attempt to cancel an active async query using dblink_cancel_query. ARGUMENTS connname Name of the connection to use. sql The SQL statement that you wish to execute in the remote database, for example select * from pg_class. RETURN VALUE Returns 1 if the query was successfully dispatched, 0 otherwise. EXAMPLES SELECT dblink_send_query('dtest1', 'SELECT * FROM foo WHERE f1 < 3'); PostgreSQL 18.6 2026 DBLINK_SEND_QUERY(3)
