OK. Given the narrow range of timestamps on the files, the most likely bet here is that you're looking at the leftovers from a "CREATE TABLE AS" or similar command that failed partway through and for some reason didn't clean up the files it'd created. As I mentioned, this'd be unsurprising if there'd been a database crash or kill -9 or something similar involved. Anyway I think you've done enough to establish that "rm'ing" those files will be safe. (But if you're paranoid you might want to save them someplace first.)

Thanks for confirming this, I will however save/backup the files before removing them (just in case anything goes wrong).
