I think it was deliberately allowed. Note that if you have a table with dropped columns which you want to make a partition of another table without them, there will need to be some physical transformation of the tuples anyway in order for reading to work; we certainly don't want to reject such cases. > > pg_dump dumps it with a normal CREATE TABLE ...

Are you proposing that if the ordering of the columns of a partition is not identical to that of its parent table, the partition should be dumped as a regular CREATE TABLE followed by ALTER TABLE .. ATTACH PARTITION, instead of a single CREATE TABLE ..
