The formatter adheres to CockroachDB rules which is why it acts like you describe. Case is insensitive in names unless you double quote it. Postgres-style (CockroachDB is one) uses "$1" for placeholders instead of "?". Adding "?" would complicate our grammar enough that it's not worth adding it.
sqlfmt is not super useful for non-postgres grammars.
Is that a thing? The Java driver must actually parse those and convert them. Java is crazy. https://github.com/mjibson/sqlfmt/issues/25 is the issue to track '?' as placeholders.
