Notice that the original has attrelid::regclass but you changed it
to attname::regclass -- that change caused the "cannot cast type
name to regclass" error that you originally reported. See the
"Object Identifier Types" section in the "Data Types" chapter of
the documentation for more info about regclass, and the "pg_attribute"
section in the "System Catalogs" chapter for more info about the
columns in that table.
