For some of the logical replication messages the data type documentedwas not correct, especially for lsn and xid. For lsn actual datatypeused is uint64 but is documented as int64, similarly for xid, datatypeused is uint32 but documented as int32.Attached is a patch which has the fix for the same.Thoughts?
There was a discussion [1] a few months ago about it. Read the Message Data
Types definition [2]. It is confusing that an internal data type (int64) has a
name similar to a generic data type in a protocol definition. As I said [1] we
should probably inform that that piece of information (LSN) is a XLogRecPtr.
Since this chapter is intended for developers, I think it is fine to include
such internal detail.
