== PostgreSQL Weekly News - January 26th 2004 ==
        Another fine week of development capped off by a late-edition weekly 
news :-) A number of items to run through and a structural change of note, so 
let's get to it.
        A couple of fixes put in this week were back-patched into the 7.4 
branch for inclusion into the next release. One fix was a missed optimization 
in the executor to avoid unnecessary projections when scanning tables where 
all columns are needed was put in, thanks to Mike Mascari for the initial 
report. Another bug in pg_dump setting incorrect database LOCATION for 7.0.* 
servers was fixed, and a problem with dropped column in pltcl triggers, 
reported by Patrick Salmon, was also fixed.
        On the main branch, some low level discussions on the GEQO algorithm, 
and close expection from Tom Lane, have lead to changes in some of the 
default GEQO parameters, knowledge of SQL heuristics inside GEQO, and 
improved documentation on the subject.Jan Wieck has also implemented a first 
pass at background writer functionality, giving folks running dedicated 
servers a way to improve variance of i/o operations of the server. Neil 
Conway spent some time cleaning up psql's memory manipulation. ECPG added 
behavioral change was put in to allow folks to set a schema search path that 
includes non-existent schema. In the past, this would have resulted in an 
ERROR, but this functionality is needed by pg_dump in some restoration cases, 
so it now emits a NOTICE. There were also a couple of documentation 
improvements including the addition of an example illustrating how to call 
functions that take composite types was added into the docs. Some examples on 
using PREPARE and EXECUTE functionality were also added.
        One last item was the final removal of the remaining JDBC Driver code 
was moved out of the main source tree and given it's own project page on 
gborg at, and of 
course will also continue to work.  Hopefully this 
will allow the JDBC folks to do more independent releases and not be tied 
down to the main source releases.
