Thanks John, I realized that and confirmed in my logs. What I'm trying to determine now, can I only log some SELECT statements, or I should log all of them or none of them.
You can configure this to multiple levels:
Global, per-user, per-database
ALTER USER postgres SET log_min_duration_statement=0;
ALTER DATABASE xyz SET log_min_duration_statement=0;
That being said, you would want to make sure that the user issuing the largest volume of queries is not set with this, otherwise, you could potential flood your logs with every single query issued. This has a tendency to cause performance problems. The other item of note is that, once logged in, the user could change that value with a similar ALTER statement.
I'm new to PostgreSQL, working on it from the point of view of Cyber Security assessment. In regards to the here is my question:
Is it a way to enable logging for psql prompt meta-commands, such as \du, \dp, \z, etc?
what the other two gentlemen are trying to say is the metacommands are shortcuts for more complex SQL queries of the pg_catalog schema, so to log them, you would need to log all queries and filter for accesses to the pg_catalog....
