- * Maps react-admin queries to a postgrest REST API
- *
- * This REST dialect uses postgrest syntax
- *
- * @see https://postgrest.org/en/stable/api.html#embedded-filters
- *
- * @example
- *
- * getList          => GET    http://my.api.url/posts?order=title.asc&offset=0&limit=24&filterField=eq.value
- * getOne           => GET    http://my.api.url/posts?id=eq.123
- * getMany          => GET    http://my.api.url/posts?id=in.(123,456,789)
- * getManyReference => GET    http://my.api.url/posts?author_id=eq.345
- * create           => POST   http://my.api.url/posts
- * update           => PATCH  http://my.api.url/posts?id=eq.123
- * updateMany       => PATCH  http://my.api.url/posts?id=in.(123,456,789)
- * delete           => DELETE http://my.api.url/posts?id=eq.123
- * deleteMany       => DELETE http://my.api.url/posts?id=in.(123,456,789)
- *
- * @example
- *
- * import * as React from 'react';
- * import { Admin, Resource, fetchUtils } from 'react-admin';
- * import postgrestRestProvider,
- *      { IDataProviderConfig,
