pg_combinebackup failure

[Kouber Saparev <kouber@xxxxxxxxx>]

Hello,

We are trying to use pg_combinebackup but eventually it fails with:

pg_combinebackup --debug --dry-run --output=/barman-backup/barman-data/test_combine 20250616T140003/data 20250617T090005/data

...

pg_combinebackup: would copy "20250616T140003/data/base/16420/2136674204" to "/barman-backup/barman-data/test_combine/base/16420/2136674204"
pg_combinebackup: would copy "20250616T140003/data/base/16420/2542449085" to "/barman-backup/barman-data/test_combine/base/16420/2542449085"
pg_combinebackup: error: file "20250617T090005/data/base/16420/INCREMENTAL.4085177931.76" has truncation block length 9501840 in excess of segment size 131072

Any idea what's wrong?
