Is there any reason why these files aren't cleaned-up ? We have just installed postgresql-9.1.3 and it seems we have this problem since this update.
I haven't checked the ratio (ls takes more than 5 minutes to return) but most of these files seems to be empty. It causes me problem when I try to tar/untar my data directory to have SR on a slave machine.
Would it be safe to have a cron script cleaining up these files once a day ? Better yet, any idea why those files are not automatically deleted when they are no longer needed ?
