Feature Request - return metadata for query columns

[ericwaldheim]

Hello,
Over at the Joe Ferner node oracle, I submitted a pull request for this feature:

joeferner/node-oracle#224

Is there any interest over here in this feature? I will submit a pull for it here if the answer is yes.
Thank you,
Eric

Sounds like a good feature. PRs are welcome!

So I've got a branch that compiles and passes all tests (including new test) on node v0.10.25.
It also compiles and passes each test (including new test) individually on node v0.11.14.

However, when running the entire test suite on node v0.11.14 for both the unmodified master and my branch, I get an error: node: double free or corruption: (transcript below). Before I spend time figuring out what's not quite right in my environment, I'd like to confirm that you have the test suite running on v0.11.14. Thank you.
