I went through documentations to try picking up this library and I think there are several things can be improved:

Major:

• Add a reading order to the documentation.
  Documentation right now are fragmented and all over the place, as a beginner after Quick Start, i dont know which one I should be reading next.
  Perhaps a proper table of content with number ordering would be nice

For a table with a column named 'default', get following output:

ALTER TABLE public.example_table ADD COLUMN default boolean NOT NULL DEFAULT false;

Resulting in a syntax error. Syntactically correct output would quote the 'default' column identifier as such:

ALTER TABLE public.example_table ADD COLUMN "default" boolean NOT NULL DEFAULT false;

DbDataAdapter.SelectQuery.SetMapper was added in #28 , lets add simple example that illustrates how to use it (map select result to several POCO models, custom mapping logic).
