             Summary: Support querying jsonb documents in Postgresql table 
                 Key: DRILL-5087
                 URL: https://issues.apache.org/jira/browse/DRILL-5087
             Project: Apache Drill
          Issue Type: Improvement
          Components: Storage - JDBC
            Reporter: Jiri Danek

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 

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.
