AI Dev Tool: PostgreSQL pgvector Hybrid BM25 + Cosine Reranker Pipeline

1. The Production Bottleneck

We engineered this zero-bloat Python 3.12+ / AsyncIO blueprint to enforce bounded concurrency, deterministic exponential backoff with jitter, strict schema validation at the ingestion boundary, and structured JSON telemetry—ready to drop into production without weeks of plumbing.

"""
AI Dev Tool: PostgreSQL pgvector Hybrid BM25 + Cosine Reranker Pipeline.

This module implements a PostgreSQL pgvector hybrid BM25 + Cosine reranker pipeline.
It utilizes bounded concurrency to manage the number of concurrent database connections.
The module can be run from the command line, and it includes a self-test and benchmark.

Usage:
    python -m ai_dev_tool --host <host> --port <port> --database <database> --user <user> --password <password>

Configuration:
    The module uses dataclasses to manage configuration. The configuration includes:
    - host: The hostname or IP address of the PostgreSQL database.
    - port: The port number of the PostgreSQL database.
    - database: The name of the PostgreSQL database.
    - user: The username to use for the PostgreSQL database connection.
    - password: The password to use for the PostgreSQL database connection.
    - concurrency: The maximum number of concurrent database connections.

Error Handling:
    The module uses exponential backoff with jitter to handle database connection errors.
    It also uses structured JSON logging to log errors and other events.
    The module includes deterministic error handling to ensure that errors are handled consistently.
