Json aggregate functions

[baszalmstra]

Is there support planned for json aggregate functions like Postgres’ json_agg/row_to_json? Would be very useful for building optimized queries for GraphQL

@baszalmstra yes, we can add support for the json aggregate function. I think after adding support for the Postgres array.
Can you create issue?)
