sharding

Create Table user:

CREATE TABLE "user" (
    id BIGINT PRIMARY KEY,
    name CHARACTER NOT NULL,
    balance INTEGER
)

Create Table payment:

CREATE TABLE "payment" (
    id BIGINT PRIMARY KEY,
    amount INTEGER NOT NULL,
    sender "user" NOT NULL,
    recipient "user" NOT NULL
)

Create Tables with using partitioning:

With rank amount from 0 to 1K:

CREATE TABLE "payment_amount_0_1K" (
    CHECK (amount <= 1000)
) INHERITS (payment)

With rank amount from 1K to 100K:

CREATE TABLE "payment_amount_1K_100K" (
    CHECK (amount > 1000 AND amount <= 100000)
) INHERITS (payment)

With rank amount from 100K to INFINITY:

CREATE TABLE "payment_amount_100K_INF" (
    CHECK (amount > 100000)
) INHERITS (payment)
