commit    b841c91c7b552fee2a0e1a665d7c5e2f28f0e078
Author:   Fujii Masao <fujii@postgresql.org>
Date:     Fri Nov 07 05:43:24 2025 +0000
First released in: 17.7, 18.1

    doc: Clarify units for io_combine_limit and io_max_combine_limit.
    
    If these parameters are set without units, the values are interpreted
    as blocks. This detail was previously missing from the documentation,
    so this commit adds it.
    
    Backpatch to v17 where io_combine_limit was added.
