You can get the timing from psql two ways:

EXPLAIN ANALYZE your_query;

Or you can use of the psql internal commands to see the this of psql internal command type "\?"
from the psql command prompt.  The one you want is "\timing".  However, notice that "\timing" and
explain analyze do not exactly agree on the results they produce.

IIRC, "\time" also counts its own overhead.
