The 8.1 installer is completely stand-alone and doesn't install any
shared libraries. It certainly won't delete anything that was already
there - that would require us to actively write code to look for and and
remove files, something we purposefully haven't done.

The client libraries are installed as a required core component,
regardless of whether you select pgAdmin. It needs to be done this way
because other components such as psqlodbc, pgoledb and even the contrib
module dblink require libpq.

It should do - in fact we package 8.1 in exactly that way after
extensive testing on XP SP2 as well as 2K3 SP1 (not to mention older
platforms).

When we build the installer it's tested on a number of clean
installations of Windows before release. Just to be sure, I just double
checked it on a clean Windows 2K3 Enterprise Server, with SP1 + patches
that I happen to be configuring at the moment. All the libraries are
found, even though none are in any shared locations (they're all in
C:\Program Files\PostgreSQL-8.1-beta3\bin).
For info, libpq requires
libiconv-2.dll
libintl-2.dll
libeay32.dll
ssleay32.dll
Comerr32.dll
krb5_32.dll

*If* each of those sub project were easily compilable in static mode on
Windows then that would probably be possible, given a few extra hours in
the day. As it is, most have very limited support for Windows, and often
finding a way to build a normal dynamic version is hard enough.
