documentationfor the GUC (neither in config.sgml or<br /> postgresql.conf.sample) suggests very very strongly that it
wasnot<br /> meant to be shipped. If we don't remove it I will certainly insist<br /> that it be documented
adequately.<br/><br /> Personally I think a hardwired #define should be plenty. What's the<br /> argument that users
willneed to tune this at runtime?<br /></blockquote></div>I tend to go in this direction too. It is unclear how it is
reallyable to improve scalability, or at least some documentation should be here to help users to set it. An additional
thoughtas well: set it with a configure switch at compilation instead of a GUC.<br />-- <br />Michael<br /></div></div>
