The previous coding failed to work correctly when we have a multi-level partitioned hierarchy where tables at successive levels have different attribute numbers for the partition key attributes. To fix, have each PartitionDispatch object store a standalone TupleTableSlot initialized with the TupleDesc of the corresponding partitioned table, along with a TupleConversionMap to map tuples from the its parent's rowtype to own rowtype. After tuple routing chooses a leaf partition, we must use the leaf partition's tuple descriptor, not the root table's. To that end, a dedicated TupleTableSlot for tuple routing is now allocated in EState. Amit Langote
PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. 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: http://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 http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
