* creating_extension is only true while running a CREATE EXTENSION or ALTER
* EXTENSION UPDATE command. It instructs recordDependencyOnCurrentExtension()
* to register a dependency on the current pg_extension object for each SQL
* object created by an extension script. It also instructs performDeletion()
* to remove such dependencies without following them, so that extension
* scripts can drop member objects without having to explicitly dissociate
* them from the extension first.
