postvec 0.5.0-2

Postvec is an extension for fused hybrid search: it combines BM25 and semantic search in one SQL call and keeps vectors in sync with your text automatically. You can also use it to migrate vectors without re-embedding of text with direct conversion between embedding formats.

Inference runs locally inside PostgreSQL or remote on postvec-server or through hosted embedding APIs.
