Andreas, Andrian,
Thank you very much for both pieces of information. It was very helpful. Now, let me ask you one more question on the same topic. Is it more granular way to control logging PosgreSQL provides, or I pretty much reduced to choosing between mod and all?
The reason I'm asking is because with 'all" volume of daily logging becomes truly ginormous. And for my purposes, I really do not need all the SELECT statements to be logged. Only those, which are responsible for explicit querying of role/privileges/roles (so, \du, \dp, \z, in essence).
Thanks,
Oleg
