Any reason you didn’t contribute to pgvector?
It would have been nice to get the support of neon in progressing pgvector - since it’s already so widely adopted by the community
(disclosure: supabase ceo)
A more important question is why supabase went with one of the slowest [0] implementations instead of building a better plugin especially since you are a VC funded company that's hardly lacking in cash. Simply gluing together a few random open source extensions is not great for developer experience.
