In addition to what Laurenz has mentioned,by default auditing does not
exist, but there are ways to add your own, some of which include:

- https://github.com/2ndQuadrant/audit-trigger
- Create views over your tables which also select a db function to log
SELECT access.
Eg.
create or replace view user_details as
select col1, col2, col3, col4, null as audit from some_table
union all select null, null, null, null, audit_function(current_user) as
func;

There are probably other options, but I can't think of any off the top of
my head at the moment. This question has come up in these lists before and
on Stack Overflow, so you might want to search around a bit for other
options.
