Hello, (Postgres 9.3.4/Linux) we have about 15 % of the files in our tablespaces that are empty and do not appear in "select pg_relation_filepath(oid) from pg_class". My guess is that a lot of them are the result of vacuuming full around 50'000 tables out of 150'000. Is there a known issue that can explain this ? We have an unusual configuration where the tablespaces are located within $PGDATA, either directly or as symbolic link... - Is there a proof mean to identify all files that are still required - A way to clean such zombies files ? regards, Marc Mamin
