PostgreSQL version: 8.2.4
Operating system: Windows XP SP2
Description: msi installer failed to upgrade to newer version
Details:
When using the win32 msi installer to upgrade server from 8.2.3 to 8.2.4,
the installer failed and gave me an error message as this: Error 1923.
Service 'PostgreSQL Database Server 8.2' (pgsql-8.2) could not be installed.
Verify that you have sufficient privileges to install system services.
But since I have the administrator privilege, there should not be any
privilege problem I think.
Steps I performed: (all were under administrator privilege)
1. clean installed ver. 8.2.3, specified a unprivilege user to run the
server process
2. run the upgrade.bat from ver. 8.2.4.
BTW. this problem do not exist for this version only, the 8.1.x series also
has the same problem.
I can provide the install log if it's needed.
