Failed to get time array

Error message

Failed to get time array

What it means

Panic from `.expect()` in SeaORM's Postgres ProxyRow conversion for `TIME[]` columns in the chrono branch. The driver decodes the column as `Option<Vec<chrono::NaiveTime>>`; when sqlx's decode fails (element type isn't `time`, or chrono array impl not compiled), the panic message is "Failed to get time array".

Solutions

1. Verify the column is exactly `time[]` and cast if needed (`col::time[]`).
2. Enable `with-chrono` and `postgres-array` features together on sea-orm.
3. Keep sea-orm and sqlx versions aligned for chrono array decoding.
4. Select the array as text and parse elements when the source type is uncontrolled.

Example fix

// before: column is timetz[]
let rows = q.map(|row| row.into_proxy_row()).await?; // panics

// after
let stmt = Statement::from_string(
    db.get_database_backend(),
    "SELECT slots::time[] AS slots FROM calendars",
);

let elem: Option<String> = sqlx::query_scalar(
    "SELECT e.data_type FROM information_schema.columns c, LATERAL (SELECT data_type FROM information_schema.element_types WHERE object_name=c.table_name AND collection_type_identifier=c.dtd_identifier) e WHERE c.table_name=$1 AND c.column_name=$2")
    .bind("calendars").bind("slots").fetch_optional(db).await?;
assert_eq!(elem.as_deref(), Some("time without time zone"));

fn is_time_array(elem: &str) -> bool { elem.eq_ignore_ascii_case("time without time zone") }

let result = std::panic::catch_unwind(AssertUnwindSafe(|| stmt_to_proxy_rows(&stmt)));
match result {
    Ok(rows) => rows,
    Err(_) => decode_time_array_as_text("slots"),
}

When it happens

Trigger: Selecting a `TIME[]` column through ProxyRow with `with-chrono` + `postgres-array` enabled and the value won't decode to `Vec<NaiveTime>` — e.g. the column is `timetz[]`, `timestamp[]`, or another array type misreported as `TIME[]`.

Common situations: Arrays of `TIME WITH TIME ZONE` elements; schema drift from time[] to interval[]; views with inferred array element types; missing `postgres-array` feature causing branch mis-selection; sea-orm/sqlx version skew.
