I changed the configuration in postgresql.conf. Following are the
changed parameters:

shared_buffers = 1GB
maintenance_work_mem = 50MB
checkpoint_segments = 64
wal_buffers = 5MB
autovacuum = off

Insert the records in the database and got a very good performance it
is increased by 6 times.

Can you please tell me the purpose of shared_buffer and
maintenance_work_mem parameter?

Thanks,
Saurabh
