postgresql[Windows XP]安装问题解决方案:
　　　　　　　　　　　　　　　　　　　　［flute0316总结］　　
　　　
最近我们做的家谱GIS要用到一些开源的东西，小组的其它成员在研究，我也没怎么抽出时间来关注．
昨天，突然想弄一下postpostgresql，就安装了一下．呵呵，遇到了几个小问题，搞了一晚上也没安好．今天上午上完课后，专心搞了一下，呵呵，成功了！

1. 首先安装JDK,并配置好环境变量

3. 安装问题："The Secondary Login Service is Not Running“
解决：从控制面板－－计算机管理－－服务里找到 Secondary Login Service 设置为自动启动。

4. 安装问题: Postgresql: Installing "Failed to set permissions" on windows XP
解决:
Postgresql: Installing "Failed to set permissions" on windows XP
Here time to test some advanced features on Postgresql,well,download 8.2.5 from their website. *.msi good,click to install.
but got error on my screen: "Failed to set PErmissions on the installed files Please see the log file in ***/tmp/pgperm.log".

checked document,it recommend NTFS,yeah,I got NTFS here. After a while,I make another approach,it worked!
--install Postgresql without set up it as windows service =>everything goes well

so the problem is clear,something went wrong when Postgresql it tryto register itself as windows service. 1 thing gave me clue quicklyafter I got this:
C:/Psql/8.2/bin>postgres
it is not allowed user with administrator privileges run Postgresql server....

the solution is: create a LIMITED user under windows,thenre-install Postgresql with windows service based on that 'LIMITED' user.

another easy day,uh? you get it. [flute0316注]:上面一段英文是要你建一个受限的计算机用户［注意重启计算机］，而不要用管理员帐户．至于为什么，我没弄明白，反正我新建一个受限帐户后，重新安装成功了．
