+ * \brief Struct for transaction commit and abort records.
+ *
+ * Struct for local and DTX commit and abort records. Only the magic distinguishes between them.
+ * Since this record must be used in the context of a valid XID, the xidsize field must not be
+ * zero. Immediately following this record is the XID itself which is xidsize bytes long,
+ * followed by a rec_tail.
+ *
+ * Note that this record had its own rid distinct from the rids of the record(s) making up the
+ * transaction it is committing or aborting.
+ *
+ * Record header info in binary format (32 bytes):
