To simplify the understanding of the compatibilty, the project now follows the Neo4j PostgreSQL extension which implements a Foreign Data Wrapper (FDW) for JSON files. Both functions must be written in a compiled language such as C, using the version-1 interface. If you write to a JSON or JSONB column then the data is See also postgres_fdw, which provides roughly the same functionality using a more modern and standards-compliant infrastructure. But postgres_fdw provides more transparent and standards-compliant syntax for accessing remote All operations on a foreign table are handled through its foreign data wrapper, which consists of a set of functions that the core server calls. # Alternatively, up to PostgreSQL 12, you can use gabfl/Multicorn that adds better support for Python3.
