Bug reference:      6371

PostgreSQL version: 9.1.2
Operating system:   Windows 7 x86
Description:=20=20=20=20=20=20=20=20

Installation stops after "Initialising the database..." without any alerts
or other actions - just show message "Initialising the database...". I
checked the data directory and all need files was there.
But no account for postgres user.
I waited for a long time. Then I broke installation.
I've already tried to install with administrator account. No differernce.

However, there is no such bug with v9.0.6.

Thank you.
