FAQ
How are missing keys handled?
The column list is the union of all object keys; missing values insert as NULL.
Are nested objects supported?
Nested objects serialize to their JSON text for JSON/JSONB columns — cast after import if needed.
Which databases are supported?
PostgreSQL and MySQL quoting out of the box; the output is also compatible with SQLite for simple cases.
