This is where I got started too. Glove embedding stored in Postgres.

Pgvector is nice, and it's cool seeing quick tutorials using it. Back then, we only had cube, which didn't do cosine similarity indexing out of the box (you had to normalize vectors and use euclidean indexes) and only supported up to 100 dimensions. And there were maybe other inconveniences I don't remember, cause front page AI tutorials weren't using it.
