My postgresql instance was last started on Apr21.
In my temp space directory, I have various files that I believe are orphaned.
Given the information below, can I safely rm the files in /mnt/iscsi/psql_tmp/tmpdata/41099 that are older than Jun 22?
If yes, should these files have been cleaned up by the restart on Apr21?
If yes, if I restart the DB today/in the next few days and the files from Jun 22 remain after the restart, can I safely rm them?
thanks,
reid
