As Tom already stated, the result of this query is a bit random since
there is no ordering at all. What are you actually querying for?

explain analyze select col01_id from table limit 1 offset 100000;
will run the query and show you how the query plan looks and how much
time is spent. It is likely to say "SeqScan" somewhere - a sequential
scan of the tabe.
