This PR adds support for DiskANN index, available on Azure PostgreSQL Flexible Server.

As it's not possible to create local unit tests for this index, I have created this PR as a draft and don't expect it to be merged.
It might be useful to some people nevertheless, as Microsoft promises better performance and less RAM usage, compared to HNSW.

Thank you Nazar Pechevystyi (@nazarpechka) for the Pull Request. At this time I would recommend adding documentation to https://github.com/langchain-ai/langchain-postgres/blob/main/examples/pg_vectorstore_how_to.ipynb to show developers how they can implement this themselves.
