Pgvector DocumentStore for Haystack?

Problem

Hi maintainers, I hope it's ok I've created an issue for this but I wanted to ask whether any of the pgvector maintainers would be interested in creating a DocumentStore integration for Haystack, our open-source framework to build LLM applications. We have support for weaviate, pinecone, opensearch, milvus and some more, and Qdrant created an external integration too. If you would be interested in creating such a document store, I know some of our community members would find it very useful.
