Not quite, because of the ability to ship absolute object file names in
the SQL script and the extension control files, edited by hackers.
The third party tool I'm talking about will have to edit those files at
packaging time in order to get the control back to where you want it.

Well, the point is that if you edit the control file, then you don't
have to care about the dynamic_library_path at all, because you're going
to setup absolute object file names (or location).

My proposal is to edit the control file module_pathname property to the
right absolute location within the new hstore binary packaging. That
responsibility is then given to the new third party tool, aimed at both
packagers and system admins.

Within the way I see things, this problem just doesn't exist, by design.

Well you know, I actually read my emails and learn from them.
