It’s my version of Postgres I believe, I’ll try to upgrade

Upgrading PostgreSQL will resolve the issue, as the current version doesn’t support the syntax used by the pgvector extension in this migration.

We also need to upgrade PostgreSQL when going to 3.5, besides installing the pgvector extension? What is the minimum required PostgreSQL version?

I don’t understand this topic. That migration runs fine on PG13.

I was running 12 :). But thanks for confirmation.

Dev migration error: PGVector

I moved to 16, but 13 might suffice.
