    3.21.2  -  bug fixes

    ----

    Fix missing closing double-quote in su -c commands in dbdpg_test_setup.pl

    ----

    3.21.0m 3.21.1:
    - New features: non-blocking async COPY FROM support (pg_putcopydata_async, pg_putcopyend_async,
    pg_flush); new string-buffer system replacing linked lists with arrays (faster)
    - Bug fixes: memory leaks fixed (PQclosePrepared cleanup path, bind_param, statement handles); float
    quoting fixes (NaN); $sth->rows() returns 0 for no-row updates/deletes; safer NUL checking in
    _dequote_bytea_hex(); allocation fixes in quote_float() /
        pg_destringify_array()
    - Fix CVE-2026-78183
