Yes, for pg_depend, no I don't know how to make that work with pointing to the extensions directly, because the whole point here is to be able to depend on a feature rather than the whole extension. Use cases: - depend on a feature f that appeared in version y of the extension (bugfix, new capability) - deprecate a feature: alter extension update removes a feature, you want to know that the dependent extensions need processing (cascade to remove them in the operation, or update them before hand, etc) (still manual operation though) I don't see how to handle those cases with a direct dependency on the extension rather than one of its features.
