Hi Bruce. I'm sorry again for being so slow, but I'm still not
understanding the initial conditions which prompted these changes. Are
you fixing something proactively, or was there a specific example of
misbehavior? The example I see in your mail with Tatsuo which now causes
trouble is for type input and output routine names, which _are_ likely
to be unique. 

Would it be possible for you to bracket the code in the cvs tree so that
we can enable/disable the old behavior? That way we can see what has
changed and how it used to behave. I suppose that would involve
bracketing code in regprocin/out and in pg_dump??
