Get time for each operation in "Explain..."

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Is there any flag I can set in PostgreSQL to get the real time spent in each step on "Explain"?
Is like "Explain Execute" that will get time for each step after real execution.
I know there is the "cost" attribute, but seems to me that the "projected cost" is not always the same as "time spent" (may be I just need more education on this topic).

Thanks,
