Hi,
I accidentally did a message-id lookup for a url of the archive. Like
https://www.postgresql.org/message-id/http%3A/archives.postgresql.org/message-id/20170914065128.a5sk7z4xde5uy3ei%40alap3.anarazel.de/
the result is an endless (presumably) redirect loop.
Not sure if worth fixing, but thought it's worthwhile mentioning.
Greetings,
Andres Freund
