Depends. Got any indexes? The more indexes you have to update the
slower it's gonna be. You can test this, it's easy to create test
rows like so:
insert into test select generate_series(1,10000);
etc. There's lots of examples floating around on how to do that. So,
make yourself a couple of tables and test it.
