Well, I know it's not an error, but it's everything i got. There was no
error shown. The command completed, but without anything imported.

As i said, the same import but with INSERT INTOs worked without any issues.
So no, there are no FK constraints failing.

But the target and source table had partitioned tables attached, using
ATTACH PARTITION.

The schema was like:
db1 schema1 public table1 (links to the listed below)
db1 schema1 subpartitions backends_y2024w03
db1 schema1 subpartitions backends_y2024w04
db1 schema1 subpartitions backends_y2024w05

The partitioning must be the problem somehow.
