First, any change like this would have to maintain their current API essentially forever, unless psycopg3 represents a
completelyincompatible break with the psycopg2 interface. There is an enormous body of code out there that uses the
currentcursor() interface for client-side cursors.
Second, it would be very unwise to make guarantees about when these operations interact with the database. I think
thatany client application should expect that both cursor.execute() and cursor.fetchone()/.fetchall() are asynchronous
operations,and code appropriately.
