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.)
