Re: logical replication empty transactions

I have reviewed the v9 patch and my feedback comments are below:

//////////

1. Apply v9 gave multiple whitespace warnings

$ git apply v9-0001-Skip-empty-transactions-for-logical-replication.patch
v9-0001-Skip-empty-transactions-for-logical-replication.patch:479:

warning: 4 lines add whitespace errors.

2. Commit comment - wording

pgoutput will also skip COMMIT PREPARED and ROLLBACK PREPARED messages
for transactions which were skipped.

=>

Is that correct? Or did you mean to say:

AFTER
pgoutput will also skip COMMIT PREPARED and ROLLBACK PREPARED messages
for transactions that are empty.

3. src/backend/replication/pgoutput/pgoutput.c - typo

+ /*
+ * If the BEGIN PREPARE was not yet sent, then it means there were no
+ * relevant changes encountered, so we can skip the COMMIT PREPARED
+ * messsage too.
+ */

Typo: "messsage" --> "message"

(NOTE this same typo is in 2 places)
