  Fixes #11569.

• Coerce strings when reading attributes. Fixes #10485.

  Example:

  book = Book.new(title: 12345)
  book.save!
  book.title # => "12345"

• Deprecate half-baked support for PostgreSQL range values with excluding beginnings. We currently map PostgreSQL ranges to Ruby ranges. This conversion is not fully possible because the Ruby range does not support excluded beginnings.

  The current solution of incrementing the beginning is not correct and is now deprecated. For subtypes where we don't know how to increment (e.g. #succ is not defined) it will raise an ArgumentException for ranges with excluding beginnings.

• Support for user created range types in PostgreSQL.
