PostgreSQL version: 8.4.4
Operating system:   Windows XP
Description:        Password error message
Details:

I need to set up a programme supported by Java and postgresql 8.4
I chose Gr8Dane$23 as my database password and successfully installed
postgradsql 8.4
When it came to launch the programme,I needed to type in the postrgadsql
password, and I got an error message "Fatal error..." I assume it was
because it did not like the $ in my password. So I uninstalled postgradsql
intending to use a password without any symbols, but now I cannot reinstall
it as I get an error message "Incorrect password". Could you reset your
database so I can reinstall postgradsql. And also advise me about what I can
use as a password, so I do not get these error messages again.
