## dblink\_error\_messagedblink\_error\_message — gets last error message on the named connection## Synopsis```dblink_error_message(text connname) returns text```## Description`dblink_error_message` fetches the most recent remote error message for a given connection.## Arguments*`connname`* Name of the connection to use.## Return Value Returns last error message, or `OK` if there has been no error in this connection.## Notes When asynchronous queries are initiated by `dblink_send_query`, the error message associated with the connection might not get updated until the server's response message is consumed. This typically means that `dblink_is_busy` or `dblink_get_result` should be called prior to `dblink_error_message`, so that any error generated by the asynchronous query will be visible.## Examples```SELECT dblink_error_message('dtest1');```
