== PostgreSQL Weekly News - April 5th 2004 == This late night edition of the weekly news is brought to you by my son Dylan, who turned 3 today :-) He found the changes inside the optimizer to be especially interesting, so let's get to it. The optimizer was tweaked a little bit to institute what is being referred to as a new "fuzzy comparison" logic. The purpose of the new code is to mark paths with the same path keys and nearly equivalent costs as redundant. While the exact amount of fuzziness may still need to be adjusted, so far it has shown good performance increases in the relevant cases with no drawbacks (ie. the results of the plans picked are the same, we just eliminate paths to get to those results a bit faster.) The GIST code saw a bit of clean up, resulting in the elimination of a problem with 64-bit strict-aligned boxes and the switch from using bytea structs to special GistEntryVector structure. Win32 also received some code cleanup that should allow it to build with VC++. Some bugs in the to_char function for handeling BC dates were fixed. On the documentation front, some information on using \df to find functions using/returning specific datatypes was included. And last, but not least, some code was put into place to lay the groundwork for allowing composite types as table columns (and potentially some other useful features as well). Finally in more international community news, our Spanish speaking friends have announced the moving of the Spanish general help list to pgsql-es-ayuda@postgresql.org. Also we're proud to announce our first mirror available in Singapore, thanks to Matthew Feinberg and Feratech.com. == PostgreSQL Product News == XpSQL version 0.9.3 is released. http://gborg.postgresql.org/project/xpsql/news/newsfull.php?news_id=163 Version 1.0.0.4 of OLE DB released http://gborg.postgresql.org/project/oledb/news/newsfull.php?news_id=164 PL/R 0.6.0-alpha released http://gborg.postgresql.org/project/plr/news/newsfull.php?news_id=165 == PostgreSQL In the News == Could open source elections close out hanging chads? http://software.newsforge.com/software/04/04/01/1530219.shtml Best of Show Award Winners Named at Bio-IT World Conference + Expo http://www.tmcnet.com/usubmit/2004/Apr/1028008.htm Aberdeen Finds Open Source Databases Show Widest Adoption in New Development http://www.prnewswire.com/cgi-bin/stories.pl?ACCT=104&STORY=/www/story/03-31-2004/0002138195 PostgreSQL and MySQL Connection Times, Round 2 (blog) http://www.randomnetworks.com/joseph/blog/?eid=101 == Upcoming Events == An Evening With Bruce Momjian: New York, NY: April 13 SRA America is sponsoring a get-together with Bruce Momjian http://www.postgresql.org/events/194.html OSCon: Portland, OR.
