Hi, thank you for updating the patch.

One comment on v4.

In v4-0002, we introduce 'commit_lsn' in the ApplyErrorCallbackArg.
This member is set for prepare, rollback prepared and stream_abort as well.
The new log message format is useful when we have a prepare transaction
that keeps failing on the subscriber and want to know the target transaction
for the pg_replication_origin_advance(), right ?
If this is true, I wasn't sure if the name 'commit_lsn' is the
most accurate name for this variable. Should we adjust the name a bit ?

Even when we decide to continue to use 'commit_lsn',
it might be better to add some comments near the definition, I feel.
