While user-defined triggers defined on a partitioned table have a catalog definition for both it and its partitions, internal triggers used by foreign keys defined on partitioned tables only have a catalog definition for its partitions. This commit fixes that so that partitioned tables get the foreign key triggers too, just like user-defined triggers. Moreover, like user-defined triggers, partitions' internal triggers will now also have their tgparentid set appropriately. This is to allow subsequent commit(s) to make the foreign key related events to be fired in some cases using the parent table triggers instead of those of partitions'. This also changes what tgisinternal means in some cases. Currently, it means either that the trigger is an internal implementation object of a foreign key constraint, or a "child" trigger on a partition cloned from the trigger on the parent. This commit changes it to only mean the former to avoid confusion. As for the latter, it can be told by tgparentid being nonzero, which is now true both for user- defined and foreign key's internal triggers.

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.
