Thank you for the reply. I have spent the better part of this week on this and related issues. 

My test procedure is as follows: create VM using Fusion 4.x with a fresh install of OS X 10.7. The VM is hosted on a Mac also running 10.7. I create a snapshot of this clean image. The first step of each test run is to restore the snapshot image. 

With this in mind, the comment about the previous installation does not seem to apply to my report. 

After considering your remarks and modifying the app install script, the app installation completes normally with a functioning PostgreSQL installation. However, the errors reported previous still appear in the logs. 

The unattended mode results in the appearance of a user "PostgreSQL" in the User Accounts preferences panel as well as the login window. It is interesting to note that a user named "postgres" in any variant does not appear in /Users/ directory, nor in the file /etc/passwd/, with the exception of the os x standard postgres account.
	$ cat /etc/passwd | grep "Postgre"
	_postgres:*:216:216:PostgreSQL Server:/var/empty:/usr/bin/false

The "one click" installer does not result in the appearance of the "PostgreSQL" user account in the os x GUI.

To recap the questions:
1. are the errors reported in the postgres install log of a type to cause a malfunction for end users?
2. how can I suppress the appearance of the user account "PostgreSQL" in the os x login window?

Many thanks,

 - Mark

> Install log shows that your db installation is successful. The error which you had sent is coming because your earlier installation failed to create 'postgres' user and when you ran the installer again, installer read /etc/postgres-reg.ini file to check any previous installation and found that previous installation was done. Hence installer tries to stop the db server in case it is running using postgres user. This command fails as postgres user was not created in your first installation because of some reason. But in latest installation (for which you have sent the log), postgres user has been created successfully and installation went successfully. You need to check why postgres user was not created in first go by checking logs of that installation.
