      See https://github.com/debezium/postgres-decoderbufs/blob/master/src/decoderbufs.c#L454-L455:

      This causes an unchanged TOAST column's value to be added to the "before" row state. This is prone to race conditions though as the value is read separately, so a wrong value may be returned in case of concurrent changes.

      Unchanged TOAST column values should never be produced as we cannot safely do it.
