Installation of PostgreSQL Service under admin account

Hello,

PostgreSQL version: 8.2.1
OS: Windows 2003 Server / Windows XP Professional

When I try installation of PostgreSQL by providing an admin account for
postgresql service user the installation fails. According to the release
notes of PostgreSQL 8.2 this is supported.
http://www.postgresql.org/docs/current/static/release-8-2.html - Drop
privileges on startup, so that the server can be started from an
administrative account (Magnus) .

Since all the services in my product run under a particular service
account it is required that PostgreSQL also runs under the same account.

Thanks in advance

Regards
Vinesh
