It might be if you could tell us how to reproduce it --- I see no
such behavior here.
In general, PG uses numerically-named files for table contents,
but they should always appear in subdirectories of $PGDATA, never
in the directory's top level. So I have no idea what those are
or what put them there. Perhaps you are using some unusual
extension or custom C code that creates them?
