This PR updates the Postgres VectorStore to the updated expectations from LangChain.

The changes are:

  • Documents added or retrieved from the vectorstore can now support the ID property
  • Support for de-duplication of ID by implementing upsert to add documents
  • Enabled support for DB Agnostic filtering (metadata filtering)
  • The (a)get_by_ids function is now supported
  • The LangChain standard suite testing is now enabled
