With postgresql-8.3-int.msi I always run into the following security error:
"Service 'PostgreSQL Database Server 8.3' (pgsql-8.3) failed to start. Verify that you have sufficient privileges to start system services."
When pressing cancel, I should expect a cleanup, but the bin and lib directories in the basedir still remain. This together with 6 postgres.exe processes ....
I am using exactly the smae options as above, and I have removed the postgres user before starting the silent install. With 8.2 I could do this over and over again, with 8.3 it seems not to work.
