No, nobody installs test versions into "real" locations. What you want
is to set an install spot with configure --prefix. For instance, I
usually doconfigure --prefix=/home/tgl/testversion --enable-debug --enable-cassert
Be sure to add $PREFIX/bin to your PATH so that you can call the
test-installation programs conveniently.
It's also often a good idea to specify a non-default port number using
--with-pgport so that you can run your test postmaster concurrently with
a regular one.
Lastly, setting PGDATA in your environment to a suitable test database
location will save typing and avoid mistakes.
As Peter mentioned, most of us have scripts to set up a preferred
working environment of this sort. I think I've published mine at least
once ... check the archives.
