It doesn’t matter when a database is attached to a connection. A savepoint is
something which affects the current transaction for a connection, which is
comprised of the INSERT/UPDATE/DELETE operations you mentioned.
One SQLite connection:
Has access to at least one database, maybe more.
Has none or one current transaction.
One transaction:
Has zero or more savepoints.
