Possible uninitialized use of the variables (src/backend/access/transam/twophase.c)

Commit https://github.com/postgres/postgres/commit/1eb6d6527aae264b3e0b9c95aa70bb7a594ad1cf, modified
data struct TwoPhaseFileHeader and added two new fields:

XLogRecPtr origin_lsn; /* lsn of this record at origin node */
TimestampTz origin_timestamp; /* time of prepare at origin node */

I think thay forgot initialize these fields in the function StartPrepare because,
when calling function save_state_data(&hdr, sizeof(TwoPhaseFileHeader));

I have one report about possible uninitialized usage of the variables.

Best regards,
