Hah, appears we allocate a relfilenode to types too, though it's not
entirely clear to me why (evidently, they're not used..).
Anyhow, adding a filter on relkind addresses it (though it's not very
future-proof, unfortunately):
SELECT
quote_ident(nsp.nspname) || '.' || quote_ident(c.relname),
s.setting || '/base/' || db.oid || '/' || c.relfilenode,
(pg_stat_file(s.setting || '/base/' || db.oid || '/' || c.relfilenode)).size as size
FROM
pg_settings s
JOIN pg_database db on (s.name = 'data_directory')
JOIN pg_class c on (datname = current_database())
JOIN pg_namespace nsp on (c.relnamespace = nsp.oid)
WHERE
relfilenode <> 0
AND nsp.nspname !~ '^pg_'
AND nsp.nspname <> 'information_schema'
AND c.relkind in ('r','i','m','p');
Thanks!
Stephen
