commit    e69030cb5178347d499bbc549213e950064564fa
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Fri Sep 06 15:57:57 2024 +0000
First released in: 18.0, 16.5, 17.0

    Fix incorrect pg_stat_io output on 32-bit machines.
    
    pg_stat_get_io() applied TimestampTzGetDatum twice to the
    stat_reset_timestamp value.  On 64-bit builds that's harmless because
    TimestampTzGetDatum is a no-op, but on 32-bit builds it results in
    displaying garbage in the stats_reset column of the pg_stat_io view.
    
    Bug dates to commit a9c70b46d which introduced pg_stat_io, so
    back-patch to v16 where that came in.
