Praveen Raja:

          I think the size of a table don't affect the speed of inserts into it.Because PostgreSQL just doing something
like"append" on the data files.
 
          But the index do speed-down the inserts. Because PostgreSQL should maintain the index when doing inserts.

          hope this is useful for your question.
