But what is about SQLAlchemy? I see nowhere a implementation of a

When implementing this myself. I am not sure if I have to use
TypeDecorator
or
UserDefinedType
as baseclass for that.
I am not sure how this would look like.
I need a list (undefined length) with tree values for each entry.
x = [(1,2,3), (1,2,3), (1,2,3)]
The JSON type would give you a quick way to handle the list format:

if you have some other string format, substitute dumps() / loads().
