Re: How to clock the time spent for query parsing and planning?

Hi Pavel,

Thanks for your reply.

My understanding is that Explain provides measurements of query run time but does not include or specifies the timing
for planning and for running optimization algorithms.  

Pls let me know if my understanding is not  correct. In that case, how do I find out how much of query time is spent to
preparethe query and how much time is spent executing it.  

Thanks,
James
