The execution plan looks like a postgresql execution plan, not a mysql

won't get mysql to work like postgresql, and any tips to speed up this
query on postgresql (which is all you can expect on a postgresql mailing
list) probably won't work on mysql.
Tried running the same in postgres and below is the plan from bothe postgres and mysql. Can you please guide me to understand , if anything else can be done to make it better?
Here's your postgres query as analyzed and made more readable by the most excellent explain.depesz.com.

Under the hints tab are suggestions to bump your work_mem to avoid writing sorts out to disk.
