Etsuro Fujita ce88170227 Disallow collecting transition tuples from child foreign tables. Commit `9e6104c66` disallowed transition tables on foreign tables, but failed to account for cases where a foreign table is a child table of a partitioned/inherited table on which transition tables exist, leading to incorrect transition tuples collected from such foreign tables for queries on the parent table triggering transition capture. This occurred not only for inherited UPDATE/DELETE but for partitioned INSERT later supported by commit `3d956d956`, which should have handled it at least for the INSERT case, but didn't. To fix, modify ExecARTriggers to throw an error if the given relation is a foreign table requesting transition capture. Also, this commit fixes make_modifytable so that in case of an inherited UPDATE/DELETE triggering transition capture, FDWs choose normal operations to modify child foreign tables, not DirectModify; which is needed because they would otherwise skip the calls to ExecARTriggers at execution, causing unexpected behavior.

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.

General documentation about this version of PostgreSQL can be found at https://www.postgresql.org/docs/18/. In particular, information about building PostgreSQL from the source code can be found at https://www.postgresql.org/docs/18/installation.html.
