SQLite adapter is NOT compatible with SQLite 3. Why Rails should continue support this antiques? I don't know. I think that only mad can say 'Lets work with rails3 (4?) but with SQLite < 3.
I suggest to stop drag this heritage and continue support only sqlite3.

Remove sqlite support from `rails dbconsole`
Support for versions of SQLite less than 3 was removed in #6011 as part
of the Rails 4.0 release. Therefore there is no need to have support for
it in the `rails dbconsole` command anymore.
