This isn't new- I've seen many cases of people happily loading gigabytes of data via INSERT with log_statement='all' on. What I don't like is the idea of springing this change on people. * Aleksander Alekseev (a.aleks...@postgrespro.ru) wrote: > I understand your concern.

Adding more options to log_statement is just an ugly route to go in, in my view.

This use-case doesn't really make much sense to me. Can you explain it in more detail? Is the goal here to replicate all of the statements that are changing data in the database? Thanks! Stephen
