Struct PgTableCursor 

pub struct PgTableCursor {
    pub after_ts: Option<String>,
    pub after_id: Option<String>,
}

Cursor for PgTableSource::iter_changes_since.

Tuple cursor (after_ts, after_id) mirrors Python commit ff01268. The (updated_at, id::text) comparison defends against silent row loss when multiple rows commit at the same boundary timestamp:

1. Row c1@T arrives → cursor advances to {after_ts: T, after_id: c1}.
2. Row c2@T arrives (same timestamp).
3. Next sync emits c2 because (T, "c2") > (T, "c1") is true.

Without the tuple cursor, a single-column updated_at > T predicate would skip c2 forever.

Fields

after_ts: Option<String>

after_id: Option<String>
