Module pgvector 

PGVector vector store (PostgreSQL + pgvector extension)

This module provides helper utilities for PGVector. The full PGVectorStore implementation requires sqlx and pgvector crates, which must be added by the user to their own Cargo.toml due to potential conflicts with rusqlite (libsqlite3-sys linkage).

To use PGVectorStore, add these to your Cargo.toml:

sqlx = { version = "0.7", features = ["runtime-tokio", "postgres"] }
pgvector = { version = "0.3", features = ["sqlx"] }

Then enable the pgvector-storage feature and include the implementation from the project’s src/vector_stores/pgvector.rs.

Functions

build_table_sql
