pgvector support

[elrhomariyounes]

Hello,

I was wondering if this api supports the pgvector extension.

Thank you.

Sure, every pg extension is supported since you have full access to SQL functions through RPC.

Now if you're looking to use pgvector operators (<#>, <=>) directly through the API then that's not possible right now. But you can always use RPC as mentioned above.

(We're looking to extend operators on #2028)

Awesome thank you for the response. In a simple case where I have a table :

CREATE TABLE items (id bigserial PRIMARY KEY, embedding vector(3));

and I want to insert a record is this correct:

curl "http://localhost:3000/items" \
  -X POST -H "Content-Type: application/json" \
  -d '{ "embedding": [1,2,3] }'

For the operators the workaround using rpc for the moment is fine

[steve-chavez]

Yes that seems fine, inserting should work normally.
