I'm not set on it, but for the existing packages -plr and -plruby we 
need a transition scheme anyway.

The chances of that are nil because createlang only supports languages 
shipped with the PostgreSQL server package.  All third-party plugins 
must be installed with some sort of SQL script.  Those scripts can be 
made to work no matter where the shared libraries are installed.

No, that won't work.

I think for now we should go with putting them in the server's 
pkglibdir.  That's easy to script, and it makes it easy for the user to 
see what's installed.  It's not like we're going to have hundreds of 
libraries there.
