Обсуждение: Removing older versions

Hi,

I installed PostgreSQL 8.4 over a PostgreSQL 8.3 installation (using msi) on
a Windows machine.

My pgAdmin3 program correctly displays only PostgreSQL 8.4 on localhost.

I went to my harddrive and noticed that I have PostgreSQL 8.3 "DATA" files
installed in: C:\Program Files\PostgreSQL\8.3

Thinking these were simply empty folders.. I tried to delete them, but I get
an error that I needed permission to do this.

I looked and there seems to be 13 megs of data files that the install
program did not delete.

How can I do this from either pgAdmin.exe or manually?

Perhaps the documentation discusses this, but I could not locate anything of
value.

there's a msi installer for 8.4?

you need windows superuser - try doing it as administrator.
ensure that the pgsql-8.3 service is not running,

or try this:

runas postgres cmd /c del /s /y C:\Program Files\PostgreSQL\8.3
