+1!

That's the thing that's really mystifying me about this whole
conversation.  It seems this compounds the work of managing extension
by requiring every extension to require an extra post-installation
step where we update everyone's search path (and that step can't be
automated because there's no way for the extension installation
process to update all of the places search_paths might be stored, even
if it could tell which ones ought to be updated).  Having a global
search_path_suffix will help with this a little bit, but I think there
are corner cases (such as the ones I mentioned upthread) where that's
not really going to be enough either.  It feels like a Java CLASSPATH,
or installing every application into /usr/local/<application-name> so
that your path has 50 bin directories in it.

It also seems to me that we're getting seriously sidetracked from the
dependency-tracking part of this project which seems to me to be a
much deeper and more fundamental issue.
