error: relation "snapshots" does not exist

Bắt đầu với ví dụ rich-text-presence và thiết lập PostgreSQL của ví dụ đó, sau đó so sánh cơ sở dữ liệu và schema được ví dụ đang chạy sử dụng với SQL tạo ops và snapshots. Tái hiện lỗi và xác nhận rằng ví dụ khởi động mà không gặp lỗi relation "snapshots".

Hi,

I keep getting this error even after creating all the tables snapshots and ops from the script provided.

CREATE TABLE IF NOT EXISTS ops (
  collection character varying(255) not null,
  doc_id character varying(255) not null,
  version integer not null,
  operation jsonb not null, -- {v:0, create:{...}} or {v:n, op:[...]}
  PRIMARY KEY (collection, doc_id, version)
);

CREATE TABLE IF NOT EXISTS snapshots (
  collection character varying(255) not null,
  doc_id character varying(255) not null,
  doc_type character varying(255) not null,
  version integer not null,
  data jsonb not null,
  PRIMARY KEY (collection, doc_id)
);
