Multiple aggregate on same type

[JeanChristopheMorinPerso]

Hello, I'm I would like to define multiple aggregate functions on one of my types: https://github.com/JeanChristopheMorinPerso/data_experiments/blob/c47bca89aab29d96a25a96a475c63a438707a9cd/conda_pgsql_rust_ext/src/lib.rs#L7-L12

I can add at least one aggregate function using the pg_aggregate macro like this:

#[pg_aggregate]
impl Aggregate for CondaVersion {
    type State = CondaVersion;
    type Args = CondaVersion;
    const NAME: &'static str = "min";
    const SORT_OPERATOR: Option<&'static str> = Some("condaversion_lt");

    fn state(
        current: Self::State,
        arg: Self::Args,
        _fcinfo: pg_sys::FunctionCallInfo
    ) -> Self::State {
        // NOTE THAT I HAVE NOT YET TESTED THIS IMPLEMENTATION
        if current <= arg {
            return current;
        }
        return arg;
    }
}

This results in

CREATE  FUNCTION "conda_version_state"(
        "this" CondaVersion, /* conda_pgsql_rust_ext::CondaVersion */
        "arg_one" CondaVersion /* conda_pgsql_rust_ext::CondaVersion */
) RETURNS CondaVersion /* conda_pgsql_rust_ext::CondaVersion */
STRICT
LANGUAGE c /* Rust */
AS 'MODULE_PATHNAME', 'conda_version_state_wrapper';


CREATE AGGREGATE min (
	CondaVersion /* conda_pgsql_rust_ext::CondaVersion */
)
(
	SFUNC = "conda_version_state", /* conda_pgsql_rust_ext::CondaVersion::state */
	STYPE = CondaVersion, /* conda_pgsql_rust_ext::CondaVersion */
	SORTOP = "condaversion_lt" /* conda_pgsql_rust_ext::CondaVersion::SORT_OPERATOR */
);

But I'm kind of failing to see how I could define a second one... Say, a max aggregate.

Is this possible with pgrx? I'm not very good at rust, so forgive me if this is more a rust question than a pgrx question.

Thanks!
