Using PARTITION OF can result in column ordering being changed from the database being dumped, if the partition uses a column layout different from the parent's. It's not pg_dump's job to editorialize on table definitions, so this is not acceptable; back-patch all the way back to pg10, where partitioned tables where introduced. This change also ensures that partitions end up in the correct tablespace, if different from the parent's; this is an oversight in ca4103025dfe (in pg12 only). Partitioned indexes (in pg11) don't have this problem, because they're already created as independent indexes and attached to their parents afterwards. This change also has the advantage that the partition is restorable from the dump (as a standalone table) even if its parent table isn't restored.

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
