There is no straightforward way of knowing if it is not reported. Suppose the session has executed SELECT * FROM A TABLE and finished. It is not executing anything therefore there is no statement text. It must be committed before the backup can proceed.
It could be safe to reset that session if you are not changing the session settings.
Version 2.3.0 avoids this situation when a session has performed selects from information schema tables, which happens when JDBCDatabaseMetaData is used.
