Re: how do i find out how long a query took?

select version();
version
-------------------------------------------------------------
PostgreSQL 7.2.1 on i686-pc-linux-gnu, compiled by GCC 2.96
(1 row)

\timing does not work gives following

oss=> \timing
Showing only tuples.
\t: extra argument 'iming' ignored

Any ideas ??? or was it just 7.2.2??
