Noteven a comment? As I said, performance results on my system<br /> were very good....<br /></blockquote></div><br
/>HiLeonardo,<br />Perhaps you could supply a .sql file containing a testcase illustrating the performance benefits you
testedwith your patch -- as I understand, the sole purpose of this patch is to speed up CLUSTER -- along with your
results?The existing src/test/regress/sql/cluster.sql looks like it only has some basic sanity checks in it, and not
performancetests. An idea of what hardware you're testing on and any tweaks to postgresql.conf might be useful as
well.<br/><br />I was able to apply your patch cleanly and run CLUSTER with it, and "make check" passed for me on OS X
aswell.<br /><br />Hope this helps, and sorry I'm not able to offer more technical advice on your patch. <br /> Josh<br
