Excellent article on Arrays. I wish I knew about these before, there have been so many times I should have used this instead of serializing / deserializing JSON myself via TextFields :(

Postgresql 9.2 supports json, btw!

You can store json, or, even better, you can write sql that returns an arbitrary json structure.

So you can have one sql query return a nested array of hashes of arrays of hashes... handy if you need a retrieve a lot of different data at once that doesn't fit into a neat set of rows.

What we need now is a function that will take an arbitrary JSON element and return a data structure associated with it. This shouldn't be too hard using plv8js.....

This could then be used as an input format for object-relational modelling.
