[求助]安装postgis时出现了create database failed，怎么办？

<P>我是gis的初学者</P>
<P>安装postsql以后（成功安装），再用postgresql的application stack builder来安装postgis，但是在安装的时候就出现create database failed</P>

<DIV class=HtmlCode>could not connect to database postgres: could not connect to server: Connection refused (0x0000274D/10061)<BR> Is the server running on host "localhost" and accepting<BR> TCP/IP connections on port 5432? </DIV>
<P>请大家帮我解决下这个问题！</P>
<P>谢谢</P>
