Re: [HACKERS] Execution time

=> How about running "time postgres ..." and connecting to the backend
=> without using the postmaster?
=> 
The time command will give the elapsed, user CPU and System CPU times.
How do I interpret it as CPU/IO time ?

Even the -s option of postgres gives those times. Will it be the same as
using "time postgres" ? Is the System time a reasonable approximation of the
I/O time and user time that of CPU time ?

Thanks
