Originally created by @LuchiLucs on GitHub (Jun 26, 2025).

Using langchain-postgres v0.0.13

Calling the code:

    my_name = "..." # Str
    my_id = "..." # Str
    pg_vector = PGVector(..., collection_name=my_name)
    await pg_vector.adelete(
        ids=[my_id],
        collection_only=True,
    )

Checking before/after the method call, the embeddings are still on the table. I tried also collection_only = False. Am I doing something wrong with my tests (tried disabling cache of my database client and revalidating connection, but the data seems to be still there).

Can someone replicate the issue?

Asking to delete, I compiled the low-level query and I found out I was using an ID saved on the metadata and not the actual ID.
