+1 to split the custom_variable_classes issue. It's a longstanding
TODO item, but EXTENSION is still very useful without the fix.
It's my guess that ExtensionSetCVC() can initialize modules one-by-one
and be called on demand, for example, at SHOW, searching pg_settings,
or assignment to variables with unknown classes.
