commit    e2f06282124b86a8ab7604c51de2dad749266fee
Author:   Nathan Bossart <nathan@postgresql.org>
Date:     Fri Jun 27 18:37:26 2025 +0000
First released in: 18.0, 13.22, 14.19, 15.14, 16.10, 17.6

    Use correct DatumGet*() function in test_shm_mq_main().
    
    This is purely cosmetic, as dsm_attach() interprets its argument as
    a dsm_handle (i.e., an unsigned integer), but we might as well fix
    it.
    
    Oversight in commit 4db3744f1f.
