Okay.  I looked at the code and I have to admit that it seems awkward to
have pg_dump left-joining everything against pg_depend and checking for
NULLs.  I wondered if there was a simpler way to go about it, perhaps
using EXCEPT?  No specific proposal though.

Thanks.  I managed to retrieve into an already-checked-out copy of HEAD
and it worked pretty well:git remote add extensions git://git.postgresql.org/git/postgresql-extension.gitgit fetch
extensionsextension:extension
 

then I could run "git diff master...extension" and see the complete
diff.  Of course, I can also see each commit individually.  Or 
"git checkout extension".

Maybe it would be worthwhile to split the parts that parse a file and
execute from a file, and submit separately.  It is obviously
self-contained and serves a useful purpose on its own.  It also forces
you to think harder about renaming the parse function :-)
