JSON Export
To export the data from a table to a JSON file, use the COPY statement:
COPY tbl TO 'output.json';
The result of queries can also be directly exported to a JSON file:
COPY (SELECT * FROM tbl) TO 'output.json';
The JSON export writes JSON lines by default. The ARRAY option can be used to write a JSON array instead.
COPY tbl TO 'output.json' (ARRAY);
For additional options, see the COPY statement documentation.
