Generalizes the lazy fetch added in GH-15287 by letting a statement choose how many rows it fetches per chunk, trading memory for speed. ext/pgsql already exposed this as pg_set_chunked_rows_size(); ext/pdo_pgsql had no way to reach it. ATTR_PREFETCH and ATTR_CHUNK_SIZE replace each other: setting one on the connection clears the other, a statement given either does not inherit the connection's value, and a chunk size of 1 or more wins when both are set on the same statement. A chunk size cannot be combined with a statement-level PDO::ATTR_CURSOR => PDO::CURSOR_SCROLL, which throws a ValueError; a connection-level chunk size is simply disabled by a scrollable statement. Requires libpq 17 or later. Close GH-23210
