Discarding the resulting rows

<table border="0" cellpadding="0" cellspacing="0"><tr><td style="font: inherit;" valign="top">Hello Hackers:<br /><br
/>Twoquestions.<br /><br />1.<br /><br />I would like to execute queries such as <br /><br />select * from part and
timethe query. But I want to ignore how much time is taken for printing the result to a file or the screen.<br /><br
/>Basically,I would like to discard the result rows after doing all the work required to execute the query.<br /><br
/>Ilooked at the documentation and I saw something about using the keyword PERFORM rather than SELECT.<br /><br />I
triedPERFORM * from part; <br /><br />But this gave me a syntax error.<br /><br />Please let me know how this can be
done.<br/><br />2.<br /><br />How do I clear the buffer caches between two query runs?<br />I believe this is not
possiblein Postgres. Can someone please confirm this or tell me how it may be done.<br /><br />Thanks,<br /><br
