I think Tom is right. I am using v5.6 of https://github.com/jackc/pgx
I quick read of the code reveals no awareness of require_auth, so I have filed an issue with the project.

What version of what client-side stack are you using? For me, libpq 16 and up recognize this parameter, while older versions fail with psql: error: invalid URI query parameter: "require_auth" If you're using some other client driver, maybe it doesn't know this parameter and guesses that it should be passed to the server. regards, tom lane
