You will be very very unhappy if you remove those files (or anything
else underneath $PGDATA). What you have there is just a 7-gig table.
We split large tables into 1Gb segments for portability reasons.
If you think that there's a lot of wasted space within the files, you
might find it profitable to use (some combination of) VACUUM FULL,
CLUSTER, or REINDEX.
