feat: Add LangChain vector store adapter for CrateDB

[amotl]

Hi there,

thanks a stack for conceiving Langflow. Hereby, we are adding another vector store adapter for CrateDB, which is effectively the same like the one for PostgreSQL/PGVector, because CrateDB is compatible with PostgreSQL.

With kind regards,
Andreas.

Hey @amotl

I was not able to run Langflow because the icon you provided is not valid. Could you take a look at it, please?

Hi @ogabrielluiz, thanks for your reply. I hope we can resolve the icon/logo issue soon. I've provided a few bits of information below, within a PR discussion thread attached to the cratedb.svg file.

Thank you. I've just amended the patch by adding the missing {...props}.

Hi @ogabrielluiz. I think this patch would be ready to be integrated now. Apologies for the woes around getting the logo right. May we humbly ask you to have a look at this again?

Hi Gabriel,

do you need anything else from us to complete this patch?

With kind regards,
Andreas.
