Incomplete support for SQLAlchemy types

[jimbobhickville]

Running into this error with a postgres numeric type which leverages decimal.Decimal under the hood:

TypeError: Decimal('1.6') is not JSON serializable

I think I see how to add it, so I'll put up a PR if I'm successful.

So I have a fix, but I had to go back a dozen commits or so to find a commit that wasn't broken to branch from. Any chance you can put the unfinished stuff into a separate branch and get master back in a clean state so I can submit a proper PR and get this fix released?

I just branched the 4.x.x branch off so you can submit the fix to there.

Thanks, I'll update my branch and get a PR up later tonight.

[jimbobhickville]

Ok, it ended up being a few days before I could get to it, but PR is up now.
