Dear hackers,

While discussing based on the article[1] with Japanese developers,
I found inconsistencies between codes and documents.

45b1a67a[2] changed the behavior when non-ASCII characters was set as application_name,
cluster_name and postgres_fdw.application_name, but it seemed not to be documented.
Previously non-ASCII chars were replaed with question makrs '?', but now they are replaced
with a hex escape instead.

How do you think? Is my understanding correct?

Acknowledgement:
Sawada-san and Shinoda-san led the developer's discussion.
Fujii-san was confirmed my points. Thank you for all of their works!
