Subject: [GENERAL] timing queries?

Is it possible to find out how long a query takes in the psql command-line
tool? For example, when I exectute a query I want to see 28ms or whatever
before the query results. If not in the command-line tool, is there a way

to

In 7.3, you can use \timing to see query duration, or SET log_duration
TO 'on';SET client_min_messages TO 'log'.

query being executed). I need this info to compare against making calls
through JDBC and through an object-layer on top of JDBC.

In 7.3 psql, just issue (at the psql prompt):

\timing

All queries subsequent to the command will have timing info.

\timing

again to toggle it off.
