Compare with:

self.define(info = {}, &block)

Eval the given block. All methods available to the current connection adapter are available within the block, so you can easily use the database definition DSL to build up your schema ( create_table, add_index, etc.).

The info hash is optional, and if given is used to define metadata about the current schema (currently, only the schema’s version):

ActiveRecord::Schema.define(version: 2038_01_19_000001) do
  ...
end

Parameters

info opt = {}
block block
