Suggestion: 3-state booleans don't require a default

[joerixaop]

I'm not quite sure why it's necessary for booleans to have a default value. Obviously when you are adding a boolean column to an existing table it may be required, because adding non-null columns requires a default in most cases. A newly created table however doesn't have a technical need for a default value for non-null tables, and it seems entirely plausible for a column not to have a good default value (whether it's an integer/string or as in this case a boolean).

Have you had a chance to check #275 #337 #43?

#43 is about where to add a default if you want to add one. I don't want to add one, but I do think a lint about booleans not being nullable is sensible, adding a requirement for a default value in that same lint makes it difficult to use when you do not want a default value .

#275 doesn't seem to have any discussion about why requiring a default would be part of the lint that requires a boolean to be not-null. The linked blog post points out what I also pointed out: a default is required when adding a column to an existing table with existing rows, that is guaranteed to be not the case when you are adding a boolean column with create_table.

I don't really understand what #337 has to do with default values (boolean or otherwise).
