Hello, I have a pgvector database with different tables such as collections, documents, embeddings, etc. From what I understand, Llamaindex has a different schema with a single table and columns for text, embeddings, etc. So, I wanted to know if it is possible to use Llamaindex on top of my existing database. thank you
Hello, I'm new to LlamaIndex and I want to use Pgvector as my vector store. How do I specify the index type (HNSW or IVFFlat) during the indexing step? I don't see any parameters specifying the index type. There is only the possibility to choose the index during querying in PgVector Query Options. But we need to specify the index type before inserting vectors, right?
