This message is CCed to Dave Page, because his name is found in startserver.vbs script discussed later.
I think there is a (minor?) problem with 8.4.5 Windows installer from EnterpriseDB (probably othere releases as well - didn't check).
Here is an abstract from the "tail" of my installation log file:
/*********************************************************/

/*********************************************************/
According to this code in startserver.vbs:
/**********************/
' Find the service
Set objService = objWMIService.Get("Win32_Service.Name='" & strServiceName & "'")
Set objService = objWMIService.Get("Win32_Service.Name='" & strServiceName & "'")
' Start it (them)
If objService.State <> "Running" Then
WScript.Echo "Starting " & objService.Name
iRetval = objService.StartService()
If iRetval = 0 Then
WScript.Echo "Service " & objService.Name & " started successfully"
Else
WScript.Echo "Failed to start the database server (" & iRetVal & ")"
WScript.Quit 1
End If
Else
WScript.Echo "Service " & objService.Name & " is already running"
End If
If objService.State <> "Running" Then
WScript.Echo "Starting " & objService.Name
iRetval = objService.StartService()
If iRetval = 0 Then
WScript.Echo "Service " & objService.Name & " started successfully"
Else
WScript.Echo "Failed to start the database server (" & iRetVal & ")"
WScript.Quit 1
End If
Else
WScript.Echo "Service " & objService.Name & " is already running"
End If
/**********************/
here is what happened on my system:
1. startserver.vbs sends a signal to Postgresql service to start: "iRetval = objService.StartService()"
2. Postgres accepted the signal and set iRetval = 0, but didn't start yet (admittedely machine was busy doing something else at the same time)
3. VB script assumes that service is started (without actually checking it's status) and proceeds trying to connect to PG (while running next installation VB script - loadmodules.vbs, according to installation log).
I realize it's a rare situation when machine will be busy with something else while installing Postgres.
But, it still can happen, and "stricter" code could avoid this problem:6
/**********************/
' Find the serviceSet objService = objWMIService.Get("Win32_Service.Name='" & strServiceName & "'")
' Start it (them)
If objService.State <> "Running" Then
WScript.Echo "Starting " & objService.Name
iRetval = objService.StartService()
If iRetval = 0 Then
Do Until objService.State = "Running"
WScript.Sleep(5000)
Loop
WScript.Echo "Service " & objService.Name & " started successfully"
Else
WScript.Echo "Failed to start the database server (" & iRetVal & ")"
WScript.Quit 1
End If
Else
WScript.Echo "Service " & objService.Name & " is already running"
End If
If objService.State <> "Running" Then
WScript.Echo "Starting " & objService.Name
iRetval = objService.StartService()
If iRetval = 0 Then
Do Until objService.State = "Running"
WScript.Sleep(5000)
Loop
WScript.Echo "Service " & objService.Name & " started successfully"
Else
WScript.Echo "Failed to start the database server (" & iRetVal & ")"
WScript.Quit 1
End If
Else
WScript.Echo "Service " & objService.Name & " is already running"
End If
/**********************/
If it really waits for service to start, checking it's status in a loop.
Same status check probably needed earlier in the script, where it's trying to start dependencies services.
oh, and I have to admit that I have zero VB scripting experience, so please correct me if my code modification is wrong.
