Hi Radek,
No doubt it will be helpful! Just make sure your blog is syndicated at
http://planetkde.org/ before you blog.
Regarding the data types, it's hard to add it in current kexi, since
kexidb is feature-frozen. Predicate is not but it's in heavy
development (refactoring) and I wouldn't like to destabilize it.

I am not 100% sure about the use case. If you mean adding lines,
points and polygons to the map (by the user), I would recommend using
some predefined XML (first define it on a wiki page).
In any kexi database there's kexi__objectdata table where you can save
extra data string related to any object (here: form and report). Query
objects use that to store SQL statements and forms use it to store
QtDesigner-like XML for UIs.
