Ah my mistake, I linked to the docs for `pg_dump` (which has long had the `format` option) rather than `pg_dumpall` (which lacks it).
Before Postgres 18 was released, the docs listed `format` as an option for `pg_dumpall` in the upcoming version 18 (e.g. Wayback Machine from Jun 2025 https://web.archive.org/web/20250624230110/https://www.postg... ). The relevant commit is from Apr 2025 (see link #0 in my original comment). But now all mention has been scrubbed, even from the Devel branch docs.
