    Description

      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.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
