This backend will work similar to the MongoDB backend and allow files to be stored in a PDO database using the Hazaar\DBI library.

Main file table:

CREATE TABLE public.file
(
    id serial,
    kind text,
    parents integer[],
    filename text,
    created_on timestamp without time zone,
    modified_on timestamp without time zone,
    length integer,
    mime_type text,
    md5 text,
    owner text,
    group text,
    mode text,
    metadata json,
    PRIMARY KEY (id)
)
WITH (
    OIDS = FALSE
)
TABLESPACE pg_default;

File data chunk table:

CREATE TABLE public.file_chunk
(
    id serial,
    file_id integer NOT NULL,
    n integer NOT NULL,
    data bytea,
    PRIMARY KEY (id),
    FOREIGN KEY (file_id)
        REFERENCES public.file (id) MATCH SIMPLE
        ON UPDATE NO ACTION
        ON DELETE NO ACTION
)
WITH (
    OIDS = FALSE
)
TABLESPACE pg_default;

While I have built this to support chunks in the database, the backend itself currently only writes a single chunk. However, reads handle multiple data chunks.
