Enum CursorDirection

    Last,

v7.39 (round 218) — FETCH / MOVE cursor direction. PG grammar: single-row forms (NEXT / PRIOR / FIRST / LAST / ABSOLUTE n / RELATIVE n) return at most one row; multi-row forms (bare n / ALL / FORWARD [n|ALL] / BACKWARD [n|ALL]) stream a run. A negative bare/FORWARD count means BACKWARD (normalized at execution).
