Yes.

I'm proposing to address a part of that problem by allowing extension
dependencies to be explicitly declared for functions and objects created
either by a user or dynamically by the extension itself—things that need
the extension to function, but aren't a part of it.

Put that way, ALTER EXTENSION doesn't sound like the way to do it. Maybe
ALTER FUNCTION … DEPENDS ON EXTENSION …? I don't particularly care how
the dependency is recorded, it's the dependency type that's important.

I'll post a patch along those lines in a bit, just so we have something
concrete to discuss; meanwhile, suggestions for another syntax to record
the dependency are welcome.
