Issue on docs

[maubaum]

Path: /tools/toolkits/database/sql

In the example of tool SQL, db_url = "postgresql+psycopg://ai:ai@localhost:5532/ai" raised an error for me. Missed library.

I solved changing to db_url = "postgresql+psycopg2://ai:ai@localhost:5532/ai"

psycopg2, not psycopg.

hey @maubaum both psycopg and psycopg2 are correct , it actually depends on user system env too , thanks 🙌
