Code review comment for lp:~rye/python-oops-tools/quote-req-vars

The problem is data that doesn't fit the schema. The schema is varchar rather than bytea, so some form of coercion is needed. The quoting is at least lossless.... We might want to change the schema as well, but I think that can wait for us to at least get the U1 oops-tools stack live with the new code, which should be soon.

Wgrant also had a fix in this area for LP itself, I'll merge them all together and either land or propose for review depending how much fix up is needed.
