== PostgreSQL Weekly News - January 19th 2004 ==
                                                                                                    
        This week seemed to pass by without to much uproar, which makes for a 
short and sweet weekly news.  I noticed a lot of the changes made tended to 
be performance related, but I think it was more by accident than design. 

	Shared memory requirements for the ARC buffer replacement strategy were 
adjusted. A misestimation of indexscan CPU costs when evaluating non-constant 
expressions compared to the index variable was corrected. Building on a 
previous optimization with IN subqueries returning DISTINCT results, the 
optimizer will also now recognize the use of UNION/INTERSECT/EXCEPT (without 
ALL) as well. Dynamically loaded C functions were sped up by adding a hash 
table to cache lookups. Initial testing indicates this should put external 
functions on par with built in functions.
                                                                                                    
        On the documentation front, We now have experimental setup for 
processing the documentation via XSLT in cvs. The plan is to test this setup 
to make sure that the results and performance are up to snuff, and then move 
to this as the primary method for building docs.
                                                                                                    
        One final note, PyGreSQL 3.4 was released this week. PyGreSQL is 
PostgreSQL interface module for Python.  You can read the full announcement
