Sure, that’s technically correct, but it’s still confusing to a user,
particularly in this cased since the error comes from running
"REFRESH MATERIALIZED VIEW" which is only applied to materialized views.

For instance, if you try running the command on a table:

CREATE TABLE a (x int);
REFRESH MATERIALIZED VIEW a;
ERROR: "a" is not a materialized view

which is what you would and should expect.
