Yeah. To enlarge on that: if you are capturing SQL commands in the
log file, they most likely contain all kinds of sensitive data ---
think credit card numbers, bank account numbers, HIPAA-protected
medical details, yadda yadda. Most of that, the database has no idea
whether it's sensitive, so "please hide sensitive data in the log" is a
non-starter. You have to guard the postmaster log about as carefully
as you guard the database contents.
