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.
