Not the end of the world but I notice when running pg_restore that I
encounter a few errors where materialized views cannot be refreshed because
they query other materialized views not yet refreshed.
Is this a fixable thing or just something one must live with, and refresh
them after the restore?

Oh? There are dependencies that are supposed to prevent that.
Can you provide a self-contained example of a schema where
that doesn't work?

Ah, you know, a little deeper: it's an issue with a mat view unable to
refresh because it uses a function, and within that function, there is a
call to a mat view not yet materialized.

Oh yes, pg_dump can't really see dependencies inside function bodies.
... Unless ... can you write the function as a new-style SQL
function (BEGIN ATOMIC instead of a string literal)?
Then I think it might work.
