LEFT JOIN pg_namespace n ON n.oid = c.relnamespace
LEFT JOIN pg_tablespace t ON t.oid = c.reltablespace
WHERE c.relkind = 'r'::"char";

Not at all, apparently. This looks to me like it will pick up every
table in the database, temporary or otherwise. Perhaps that's not a
good idea ...

You need to pay attention to the schema it was found in.
"has_schema_privilege(schemaname, 'USAGE')" might be a suitable filter.
