Not much to say here --- does what it says on the tin. The "binary" representation in each case is really just the same as the text format, though we prefix a version-number byte in case anyone ever feels motivated to change that. Thus, there's not any expectation of improved speed or reduced space; the point here is just to allow clients to use binary format for all columns of a query result or COPY data. This makes use of the recently added ALTER TYPE support to add binary I/O functions to an existing data type. As in commit a80818605, we can piggy-back on there already being a new-for-v13 version of the ltree extension, so we don't need a new update script file.
