Index DDL cascading on partitioned tables introduced a way for ALTER TABLE to be called reentrantly. This caused an an important deficiency in event trigger support to be exposed: on exiting the reentrant call, the alter table state object was clobbered, causing a crash when the outer alter table tries to finalize its processing. Fix the crash by creating a stack of event trigger state objects. There are still ways to cause things to misbehave (and probably other crashers) with more elaborate tricks, but at least it now doesn't crash in the obvious scenario. Backpatch to 9.5, where DDL deparsing of event triggers was introduced.

Test extensions and libraries ============================= src/test/modules contains PostgreSQL extensions that are primarily or entirely intended for testing PostgreSQL and/or to serve as example code. The extensions here aren't intended to be installed in a production server and aren't suitable for "real work". Most extensions have their own pg_regress tests or isolationtester specs. Some are also used by tests elsewhere in the tree. If you're adding new hooks or other functionality exposed as C-level API this is where to add the tests for it.
