You can use "\timing" to switch timing on/off, and you can use explain
and explain analyse.

09:33 < akretschmer|home> ??explain
09:33 < rtfm_please> For information about explain
09:33 < rtfm_please> see http://techdocs.postgresql.org/oscon2005/robert.treat/OSCON_Explaining_Explain_Public.sxi
09:33 < rtfm_please> or http://www.postgresql.org/docs/current/static/sql-explain.html

Btw.: please no HTML, and please don't hijacking other threads.
