The only PostgreSQL schema you need, for Graph data.

Here is basically what I'm going to use.

```sql
SET client_encoding = 'UTF8';

CREATE TABLE link_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
);

CREATE TABLE base_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
  code BOOLEAN
);

CREATE TABLE code_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
  code BYTEA
);

CREATE TABLE date_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
  code DATE
);

CREATE TABLE fork_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
  code NUMERIC(8,2)
);

CREATE TABLE form_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
  code INTEGER
);

CREATE TABLE line_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
  code CHARACTER VARYING(255)
);

CREATE TABLE load_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
  code JSON
);

CREATE TABLE race_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
  code TIMESTAMP WITH TIME ZONE
);

CREATE TABLE text_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
  code TEXT
);

CREATE TABLE time_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
  code time without time zone
);

CREATE TABLE tune_list (
  mark BIGSERIAL PRIMARY KEY NOT NULL,
  home BIGINT,
  name CHARACTER VARYING(255),
  code REAL
);

CREATE INDEX base_code_index ON base_list USING btree (code);
CREATE INDEX base_home_name_index ON base_list USING btree (home, name);

CREATE INDEX time_home_name_index ON time_list USING btree (home, name);
CREATE INDEX tune_home_name_index ON tune_list USING btree (home, name);
```

One table per datatype, essentially, and one table for links. Everything has a name. BigInteger sequences for the IDs so they can grow pretty large. The queries are the hard part, trying to figure out how to serialize your standard JSON records from something like this.
