Re: YAML Was: CommitFest status/management

Can I ask the final decision whether the YAML formatter should be
applied or rejected?  As far as I read the discussion, we can apply it
because serveral users want it and we don't have a plan to support
extensible formatters in the core.

Comments from additional discussion:

  - YAML format is the second (or the best for some people)
    human-unreadabe format for EXPLAIN output.

  - JSON is not always a subset of YAML. It is not recommended to
    generate/parse YAML with a JSON generator/parser or vice versa.

  - We won't add any core hooks and plug-in to format EXPLAIN output.
    Client tools may convert the output if needed. (ex. using XLST)

  - The spec of YAML might be changed in the feature, but we use
    only the basic parts. The parts will not be changed.
