That could happen, for example, if the partitioning column is of type text and the two systems have different definitions of the collation used to sort the partitioning column. --lock-wait-timeout=timeout Do not wait forever to acquire shared table locks at the beginning of the dump. ...
For example, if the older version PostgreSQL is running on port 5432, start the new cluster on port 5433. If you are upgrading and migrating the database to a different server, create a new cluster using new binaries on the target server – the cluster may not need to run on a ...

restoring data on a server where rows do not always fall into the same partitions as they did on the original server. That could happen, for example, if the partitioning column is of type text and the two systems have different definitions of the collation used to sort the partitioning ...
