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 file
from 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');

file
---------
1434986
1434984
1434985
(3 rows)

[root(at)DB1 16384]# ls -la 143498[456]*
