📄 Description


vectorstore = PGVector(
        embeddings=embeddings,
        collection_name=collection_name,
        connection=connection,
        use_jsonb=True
    )

I found a small bug when I created PGVector class. I wanted to use Table that I already created but in original code, PGVector initializes collection_name with default collection name variable :_LANGCHAIN_DEFAULT_COLLECTION_NAME.

I hope you check this out ! Thank you .
