I played with this a little.  What would be the proper solution?
Doesn't the backend go and cd to the data directory.  I blindly
tried:
    as 'plpgsql.so' language 'c';
and
    as 'lib/plpgsql.so' language 'c';

and it can't find the file.  Is there a way to correctly reference the
lib directory associated with the execuables directory structure?

One of the examples in the docs shows the full path, too. At the bottom
of this URL:
