Do we really need a specialized vector database?
It feels like Postgres is eating the world. In a thread a couple of days ago many argued that with the capability of efficiently storing and processing JSON we can do without MongoDB et al. Now we also replace vector databases. 
There are extensions that provide columnar storage and to be honest I never completely understood the need for specialized time series databases.<p>It is a bit as if Postgres has become what Oracle wanted to be - a one-stop solution for all your data storage needs.
