Description

Let's have a Postgresql database with a table with one column of jsonb values. I wish to be able to treat this column as a collection of JSON documents and be able to work with it in Drill the same way I can if they were stored in MongoDB.

That is, I want to query the JSON documents from Drill and have Drill produce Postgresql queries that take advantage of Postgres' json querying operators and indexes I made in Postgresql inside this column. (see https://www.postgresql.org/docs/9.5/static/datatype-json.html 8.14.4. jsonb Indexing).

What I do not want is to pull all the json from Postgresql in the string representation and then have to reimport it into say MongoDB.
