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.
