get user info on log

When using set role or set session authorization and an error occurs I
get user name which logged in and not the one I´ve changed to.

There is a way to get session_user and current_user on log ?

When I do:

test(5432)=# set role maura;
ERROR: role "maura" does not exist
test(5432)=# SET SESSION AUTHORIZATION 'maura';
ERROR: role "maura" does not exist

I get:

psql-postgres-2022-09-15 08:53:41.204 PDT-0ERROR: role "maura" does not
exist
psql-postgres-2022-09-15 08:53:41.204 PDT-0STATEMENT: set role maura;
psql-postgres-2022-09-15 08:55:26.325 PDT-0ERROR: role "maura" does not
exist
psql-postgres-2022-09-15 08:55:26.325 PDT-0STATEMENT: SET SESSION
AUTHORIZATION 'maura';

in the logs.

Are you not seeing that or do you want something different?

If you want something different then you will need to provide a more
detailed description of what that is.

Thanks

No, I was asking about an error occurring later, not on set session

authorization command.

set role maura;
--user Maura exists and set was done correctly
--now I´m working as Maura
select 1/0; -- I would like to see this exception on log being logged as
maura

Hi,

You can use log_line_prefix in postgresql.conf to log the user name into
the logs.

That uses the session user, the user that established the connection.
What the OP is after is the role name that is set by SET ROLE or SET
SESSION AUTHORIZATION.

To illustrate:

psql -d test -U postgres

test(5432)=# select session_user, current_user;
session_user | current_user
--------------+--------------
postgres | postgres

test(5432)=# set role aklaver;
SET
test(5432)=> select session_user, current_user;
session_user | current_user
--------------+--------------
postgres | aklaver
(1 row)

test(5432)=> select 1/0;
ERROR: division by zero

From log with log_line_prefix of log_line_prefix = '%a-%u-%m-%x'
:

psql-postgres-2022-09-17 14:36:06.635 PDT-0ERROR: division by zero
psql-postgres-2022-09-17 14:36:06.635 PDT-0STATEMENT: select 1/0;

Ganesh is looking for psql-<current_user> not psql-<session_user>, in
this case psql-aklaver.

Ganesh Korde.

I don't know of a way to get this.
