pg-cloudflare: Workaround typescript bug regarding Buffer.from

Fixes the following error:

    % yarn build
    yarn run v1.22.19
    $ tsc --build
    packages/pg-cloudflare/src/index.ts:156:29 - error TS2769: No overload matches this call.
      The last overload gave the following error.
        Argument of type 'ArrayBuffer | Uint8Array<ArrayBufferLike>' is not assignable to parameter of type 'WithImplicitCoercion<string> | { [Symbol.toPrimitive](hint: "string"): string; }'.
          Type 'ArrayBuffer' is not assignable to type 'WithImplicitCoercion<string> | { [Symbol.toPrimitive](hint: "string"): string; }'.
