You might want to check out the docs at

<http://developer.postgresql.org/docs/pgsql/src/tools/backend/index.html>

and

<http://www.ca.postgresql.org/users-lounge/docs/7.2/postgres/mvcc.html>

to learn the answers to these questions. There's no general answer
to your question, exactly, since you talk about insert, copy, and
update.
