A few minor comments:

(1) doc/src/sgml/protocol.sgml

In the following description, is the word "large" really needed? Also
"the message ... for a ... message" sounds a bit odd, as does
"two-phase prepare".

What about the following:

BEFORE:
+                Identifies the message as a two-phase prepare for a
large in-progress transaction message.
AFTER:
+                Identifies the message as a prepare for an
in-progress two-phase transaction.

(2) src/backend/replication/logical/worker.c

Similar format comment, but one uses a full-stop and the other
doesn't, looks a bit odd, since the lines are near each other.

* 1. Replay all the spooled operations - Similar code as for

* 2. Mark the transaction as prepared. - Similar code as for

(3) src/test/subscription/t/023_twophase_stream.pl

Shouldn't the following comment mention, for example, "with streaming"
or something to that effect?

# logical replication of 2PC test
