Hi,

Is there a way to track “transactions” by default (i.e. without anyone having
set up anything specific). The problem I am facing is that users are claiming
that settings are disappearing with them doing anything to affect them. It
would be good to be able to see what postgresql thinks is going on.

*Subscriber adds Severity/BU/Service by ticking the corresponding box in
subscriber configuration in WEBAPP. This works for some time.

*Subscriber stops receiving selected [tickets].

*Upon checking settings the selected Severity/BU/Service has been unselected.
Not "without anyone having set up anything specific", but you can change the
setting in postgresql.conf to: log_statement = 'all' and reload the settings.
You can now see all SQL executed in the log and can debug what's going on. --

Hi Karl Martin,

you could set log_min_duration_statement=0 at the global level (in the config file) or at session level too.

regards,

fabio pardi

How much impact on performance and disk space would this or
set log_min_duration_statement=0
have?

I have no idea as to how common this is, or when it happens, so it would need to run until this reported again (or some reasonable time if it doesn’t happen).

Well, the answer here is of course "it depends"... If you have lots of
activity the logs will fill up quite quickly, but you can easily test this in
production and just turn off logging again by setting it to 'none' and reload
settings (no need to restart). You can also only log modifications by setting
log_statement = 'mod' Also watch out for triggers modifying stuff. -- Andreas

If what you need is business-like trail to specific relations (tables) (most probably what you need) then you may find pgaudit very useful. Its author dwsteele also wrote pgbackrest, as a tool it
works wonders and the support is superb.

In addition to what Andreas has suggested, you should also verify user
claims by
A. Have them show you the query they executed,
B. Verify they have appropriate SELECT, INSERT, UPDATE ad/or DELETE
permissions
on the tables involved.
