I thinking about some simple API, that can be based on transformation
to text. It can be enough for almost all.

* text[] = record_to_array(record)
* table(id, key, datatype, value) = record_to_table(record)
* text = record_get_field(record, text)
* record = record_set_field(record, text, anyelement)
