     Type:  enhancement      |      Status:  new          
 Priority:  low              |   Milestone:  PostGIS 1.5.2
Component:  postgis          |     Version:  1.5.X        
 Keywords:  win32-installer  |  
-----------------------------+----------------------------------------------
 When installing PostGIS on Microsoft Windows, the installer shows a
 "Database Connection Information" dialog to supply User Name, Password,
 and Port. The installer will begin to install PostGIS, however, if there
 is a mistake in the connection information, the installer fails part-way
 in, requiring it to be run again from the beginning.

 It would be nice to allow multiple attempts to correct the connection
 information, if say, there was a typo with the password. This way the
 installer only needs to be run once (for example, using Application Stack
 Builder, which downloads the installer to {{{%TEMP%}}}).

 Not only should the connection info establish a connection to a database,
 but {{{select count(*)=1 from pg_user where usename=$1 and
 usecreatedb;}}}. If there is an error, the user should be able to go back
 and correct, try again, repeat or cancel. Correct connection info should
 be established before starting the install process.
