I'm not sure this would be worth the effort - I'll grant it would be cute,
but getting pg_dump to understand SQL seems a little ambitious. We'd
probably end up defining a portable schema definition language just for
dump files.
To achieve Tom's suggestion it might be simpler to store two versions - the
'full' version, and the 'fully deconstructed' version. If our analysis of
the dependencies meant we needed to break up an object, then we use the
latter.
