Since tuple-routing implicitly checks the partitioning constraints at least for the levels of the partitioning hierarchy it traverses, there's normally no need to revalidate the partitioning constraint after performing tuple routing. However, if there's a BEFORE trigger on the target partition, it could modify the tuple, causing the partitioning constraint to be violated. Catch that case. Also, instead of checking the root table's partition constraint after tuple-routing, check it beforehand. Otherwise, the rules for when the partitioning constraint gets checked get too complicated, because you sometimes have to check part of the constraint but not all of it. This effectively reverts commit 39162b2030fb0a35a6bb28dc636b5a71b8df8d1c in favor of a different approach altogether. Report by me. Initial debugging by Jeevan Ladhe. Patch by Amit Langote, reviewed by me. Discussion: http://postgr.es/m/CA+Tgmoa9DTgeVOqopieV8d1QRpddmP65aCdxyjdYDoEO5pS5KA@mail.gmail.com
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: 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/.
