Switches the production backing store from SQLite to PostgreSQL 16, per DR-2.
The migration trigger is two concurrent writers on the my-deepagent ORM
tables — which first appears with FastAPI (M8-Py). Doing the cut now keeps
the surface area small while M8-Py is still planning.
Production deps: `asyncpg`, `psycopg[binary]`, `langgraph-checkpoint-postgres`.
Test deps: `aiosqlite` (the bulk of unit + integration tests stay on sqlite
tmp_path for speed; the E2E suite and the new checkpointer tests exercise
the live Postgres path).
Highlights
- `persistence/db.py`: dialect-aware connect listener. SQLite still gets
WAL + busy_timeout=5000 + foreign_keys=ON; Postgres gets `SET TIME ZONE 'UTC'`.
Added `Database.dialect_name` + `drop_schema` (test-only).
- `persistence/checkpointer.py`: SqliteSaver → AsyncPostgresSaver. API is
now async (`async with`) and takes a connection string. SQLAlchemy URL
prefixes (`+asyncpg`, `+psycopg`) are auto-stripped to a plain libpq DSN
(`_to_psycopg_dsn` helper, 4 unit tests).
- `persistence/upsert.py` (new): `insert_for(session)` — dialect-aware UPSERT
helper. Picks `postgresql.insert` or `sqlite.insert` based on the bound
engine. Replaces 5 hardcoded `sqlite_insert` call sites in `budget.py`,
`recovery.py`, `cli/doctor.py`.
- `persistence/models.py`: `RunRow` partial unique index declares both
`postgresql_where=` and `sqlite_where=` for cross-dialect correctness.
- `config.py`: default `database_url` now
`postgresql+asyncpg://devflow:devflow@localhost:55432/mydeepagent`. v3
`devflow` DB preserved untouched; v4 lives in a fresh `mydeepagent` DB.
- `cli/doctor.py` check 8: dialect-aware DB liveness probe. Postgres path
runs `SELECT 1` (pg_isready equivalent); SQLite keeps `PRAGMA integrity_check`.
- `alembic/env.py`: env-aware URL resolution (`MYDEEPAGENT_DATABASE_URL` >
`DATABASE_URL` > default). Async driver prefixes are mapped to the sync
equivalents alembic needs.
- `alembic/versions/9f2a6c79667e_v0_2_baseline_schema_postgres.py` (new):
fresh baseline autogenerated against live Postgres. Old SQLite migrations
(`79945fdc2649`, `839f2233e346`) deleted — v0.2 starts a clean history.
- `tests/conftest.py` (new): `pg_db_url` async fixture creates a fresh DB
per test against docker-compose `devflow-postgres` and drops it on
teardown after terminating lingering backends.
- `tests/integration/test_checkpointer.py`: rewritten for AsyncPostgresSaver
(4 pure DSN-converter unit tests + 3 async context-manager integration tests).
- `tests/integration/test_e2e_workflow.py`: switched to `pg_db_url`. Real
OpenRouter E2E now exercises the production Postgres path end-to-end.
Recovery
- Previous SQLite database at the platformdirs data_dir is NOT auto-migrated;
v0.1.0 was the only release that wrote to it. Set
`MYDEEPAGENT_DATABASE_URL=sqlite+aiosqlite:///<path>` to read it.
- The v3 `devflow` Postgres DB is preserved untouched (separate database
name); to inspect: `psql -h localhost -p 55432 -U devflow -d devflow`.
Gates
- ruff check + ruff format --check + mypy --strict: PASS (102 source files)
- pytest non-E2E: 576 PASS (5.46 s)
- pytest E2E real OpenRouter on Postgres: 1 PASS (122.93 s, ~$0.05/run)
--no-verify: lefthook still TS-only (deleted in 0e61b2d but still queryable
in git history).
