How about a slightly modified version like: (a) The LSN of the abort
operation, present only when the change stream can be applied in
parallel. This field is available since protocol version 4. (b) Abort
timestamp of the transaction, present only when the change stream can
be applied in parallel. The value is in number of microseconds since
PostgreSQL epoch (2000-01-01). This field is available since protocol
version 4.
