Ask a natural-language question about PostgreSQL development. The answer is generated only from the pgsql-hackers mailing-list archive — retrieved by hybrid semantic + keyword search, then synthesized with citations to the exact source messages. If the archive doesn't cover it, you'll be told so rather than given a guess.

This feature runs a small local model (qwen2.5, GPU) over retrieved archive passages. It can still be wrong or miss context — always read the cited source messages. Rate-limited; heavy use may be throttled.
