Greetings,

 

I have a large table (~90 million rows) containing vessel positions.

  ...



Could you kindly provide a script to create the table and populate it with several sample
rows, please? Also, provide the desired output for the sample rows.

It would be good to take a look on the “EXPLAIN ANALYZE” output of your query,
please, share http://explain.depesz.com/ link.
