Monkey patch for Sequel to support table inheritance in create_table. Not pretty, but functional.

sequel_schema_inheritance_patch

module Sequel
  class Database
    def create_table_from_generator(name, generator, options)
      sql = create_table_sql(name, generator, options)

      if options.has_key? :inherits
        sql = "#{ sql } INHERITS (#{ options[:inherits] })"
      end
      execute_ddl(sql)
    end
  end
end

# Usage
WH.create_table :some_table, { inherits: 'some_parent_table' } do
  primary_key :some_id, name: :some_table_some_id
end
