Yes, I thought this as well in the beginning, but as Radim confirmed, each
database backend supports different types of data, so it would be either very
limiting (just show some basic data types supported by all backends) or very
complicated (make a list of data types with a note on which backend supports
them or not...).

What do others think ?

Which data types are common to all backends ?

I guess its about finding the compromise between "newbie-friendly" and flexible.

Feedback very welcome.
