1445043649 d312bdf968 test(config): pin default postgres backend + sqlite regression
新建 backend/tests/test_default_database_backend.py 两个测试:

  - test_explicit_sqlite_backend_still_works (T2.3)
    显式 database.backend=sqlite 仍生效;防 PR2 改默认后 SQLite 用户
    悄无声息 regression
  - test_config_example_default_backend_is_postgres (T2.4)
    直接读 on-disk config.example.yaml,断言 database.backend == 'postgres'
    且 postgres_url == '\$DATABASE_URL'(不允许硬编码凭据)

Stage 0 PR2 T2.3 + T2.4.

"""Stage 0 PR2 · default backend regression + sqlite-still-works.
Two facts pinned here:
T2.3 — explicit ``database.backend: sqlite`` still produces a working
config (backwards-compat for users who deliberately stay on SQLite).
T2.4 — ``config.example.yaml`` default ``database.backend`` is ``postgres``
(Stage 0 PR2 flipped this from sqlite).
