Track relations error: json ->> boolean #150
Description
I'm trying to use the graphql-engine on top of my Django application, however I'm getting the following error when I try to add any relation (even ones that don't really use the JSON type). This is happening on PostgreSQL 9.4 -- is there a minum version requirement?
