community[patch]: Use SQLAlchemy's `bulk_save_objects` method to improve insert performance (#16244)
- **Description:** Improve [pgvector vector store
adapter](https://github.com/langchain-ai/langchain/blob/v0.1.1/libs/community/langchain_community/vectorstores/pgvector.py)
to save embeddings in batches, to improve its performance.
  - **Issue:** NA
  - **Dependencies:** NA
  - **References:** https://github.com/crate-workbench/langchain/pull/1


Hi again from the CrateDB team,

following up on GH-16243, this is another minor patch to the pgvector
vector store adapter. Inserting embeddings in batches, using
[SQLAlchemy's
`bulk_save_objects`](https://docs.sqlalchemy.org/en/20/orm/session_api.html#sqlalchemy.orm.Session.bulk_save_objects)
method, can deliver substantial performance gains.

With kind regards,
Andreas.

NB: As I am seeing just now that this method is a legacy feature of SA
2.0, it will need to be reworked on a future iteration. However, it is
not deprecated yet, and I haven't been able to come up with a different
implementation, yet.

community: Allow deleting by ID and collection in `pgvector` (#15627)
- **Description:** The `delete_collection` method deletes an entire
collection regardless of custom ID. The `delete` method deletes
everything with the provided custom IDs regardless of collection. It can
be useful to restrict deletion to both the collection and a set of
custom IDs. This change adds support for that by allowing you to
optionally specify that `delete` should be restricted to the collection
defined on the `PGVector` instance.

Added more filtering options to pgvector vectorstore (#14852)
- **Description:** Using PGVector vector store, it was only possible to
filter for values equals, in or not in metadata. Extended this feature
to work with the following keywords : IN, NIN, BETWEEN, GT, LT, NE, EQ,
LIKE, CONTAINS, OR, AND
