Description:        Uninstall v8.0 removes files v8 Beta4 is dependant on.
Details:

I installed release v8.0 in a seperate directory from my beta4 installation
and then uninstalled it.  This removed at least one of the shared files the
beta was dependant on.  When I try to start the beta as a service I get
"pg_ctl.exe - Unable To Locate DLL" pop-up with the following information:

The dynamic link library libpq.dll coud not be found in the specified path
C:\Tools\PostgreSQL\8.0.0-beta4\bin;C:\WINNT;... (etc., rest of the path
deleted).

I know I should not speculate, but there is some risk that someone will
install the release and then uninstall a beta (after configuring and testing
the release) and break the release installation.
