Yes, in that you cannot link directly to another DLL on Windows (without
hoop jumping and lots of pain), you link to the import library. So if we
don't generate an import library then (eg) MyExtension cannot link to
hstore.dll . It can still look up function exports via the fmgr.

As concluded upthread, it's easier to just generate import libraries for
everything since we need it for the client library, so nothing's going
to change anyway.
