8.1.3 and unused files

Am I correct in the thought that the various files listed below are not
used by the database and can be safely removed? There were no other
active db connections when I issued this command.

I think truncate (Slony) left them behind.

ssdb=# select filefrom pg_ls_dir('base/'|| (select oid from pg_database where datname =
'ssdb')) as tab(file) where file !~ '\\..*$'and file not in (select relfilenode from pg_class)and file not in
('PG_VERSION','pgsql_tmp');
