I have sent an email to those who are working on CI to let them know
the CI is partly broken and the fix has been proposed.
https://www.postgresql.org/message-id/20260622.192319.148395607405547262.ishii%40postgresql.org

Once the fix is installed, the patch does not need to be part of
v50. Let's wait for a while.
