Re: Support for OUT parameters in procedures

Jdbi got a feature request for such parameters a while back:
https://github.com/jdbi/jdbi/issues/1606

The user uses Oracle which I don't really care to install. When I tried to
implement the feature using Postgres,
I found the driver support too lacking to proceed.

So there's some interest out there in making it work, and I can volunteer
to at least smoke test it with my test cases...
