1) Which Postgres version?

2) What pg_dump options did you use?

3) What output/error do you get?

4) What does the database schema look like?  Are you using table
   inheritance or foreign keys for the parent-child relationship?

We are using 14 version
Pg_dump with  -Fp and --loading-via-parent-root option 



Database name is better and schema is better. ..



Thanks

There is no such option "--loading-via-parent-root"

It’s actually named —load-via-partition-root ; close enough if going from memory I’d say…but better still to copy and paste real commands or reproducible scripts.

But how are the tables defined, i.e., the CREATE TABLE statements?

Are we talking about table partitions when you're possibly using
--load-via-partition-root (as noted downthread)?
