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.
