Oh ok. Not to cause confusion, but after I suggested I would request an update to the docs, I thought maybe it would be better to ask if the VTU's code could be modified to include MVs. So I sent a request to pgsql-hackers (I think that's the list to use for feature requests). But from what you're saying, Tom, that may be a fruitless endeavor. If they reply back "nope", then I'll submit a request to have the documentation updated.
Thanks for everyone's contributions!

The reasoning is that the information_schema views are defined by the
SQL standard and therefore should only show content that matches the
standard. Thus, they ignore PG-invented objects like matviews and
sequences. Some other projects adopt more liberal views about
what should be shown in those views, but that one is our policy.
