How to convert the entire database to JSON?

Question

Python

Good! I don't understand python and db, maybe the question is obvious. There is a DB, I want to transform all DB in json. It turned out to convert each table to json, but is it possible to convert the entire database with one command?

Answer 1

Answer 2

select json_agg(tablename) from tablename;
