Thanks a lot for creating the RFC.

I have just two comments:
- is the alternation of hte field definition going to have some rules
how the existing data should be converted to the new type or will the
driver itself choose how to convert the data? The latter option is
surely the easier one, but it would be probably good to guarantee at
least some expected conversions: int <-> text, float <-> text, round
the number when lowering precision etc.
- what is actually the motivation behind reordering of the fields? Is
that just for aesthetical reasons? (e.g. zip code should be next to
the city name)
