More informative query time about mgconsole

[gitbuda]

Yes, at the moment mgconsole is just printing out the "wall_time" in the following format:

N rows in set (0.001 sec)

While the underlying client actually has the following info available:

• cost_estimate
• parsing_time
• planning_time
• query_execution_time

I think the mgconsole should be extended in two ways:

1. By default, the output should be N rows in set (round trip in 0.001 sec) (to make it clear what is the time about)
2. Add, e.g., --varbose-query flag where the other stuff would also be printed out

There is also another angle, from the client's perspective there are many viable times to present:

• round trip or time for the results being available
• time to make data consumable
• time to consume the data (in this case, printing them out)

That seems like useful information! However, from the benchmarking perspective, there is currently no way to measure performance from client. Adding that in some way would help me as a developer to better understand queries.

What exactly would be helpful to measure and print out?

The pure query execution time, and planning time. The closest information to this is a PROFILE query that breaks that information by different execution cursors.
