Beginning in v15, if you apply ALTER TABLE ENABLE/DISABLE TRIGGER to a partitioned table, it also affects the partitions' cloned versions of the affected trigger(s). The initial implementation of this located the clones by name, but that fails on foreign-key triggers which have names incorporating their own OIDs. We can fix that, and also make the behavior more bulletproof in the face of user-initiated trigger renames, by identifying the cloned triggers by tgparentid. Following the lead of earlier commits in this area, I took care not to break ABI in the v15 branch, even though I rather doubt there are any external callers of EnableDisableTrigger. While here, update the documentation, which was not touched when the semantics were changed. Per bug #17817 from Alan Hodgson. Back-patch to v15; older versions do not have this 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. 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.
