I have a flat file of facts from my puppet master, but Octofacts does not like it. In particular it trips up on the following YAML:

pe_postgresql_info:
  installed_server_version: "9.6"
  data_partition_size_bytes: 804913152000
  data_partition_available_bytes: 598647898112

      used_bytes: 100328099840

When I use the fact file in a test, I get the following error:

     NoMethodError:
       undefined method `to_sym' for 9.4:Float
       Did you mean?  to_s
