Hi Holger,

Okay, I added the output with \x option:  

show statement_timeout ;
-[ RECORD 1 ]-----+---
statement_timeout | 2h

show max_standby_archive_delay ;
-[ RECORD 1 ]-------------+---
max_standby_archive_delay | 2h

show max_standby_streaming_delay ;
-[ RECORD 1 ]---------------+---
max_standby_streaming_delay | 2h

SELECT usename, state,wait_event, backend_xmin,xact_start,query_start,state_change,now() FROM pg_stat_activity WHERE backend_xmin IS NOT NULL ORDER BY age(backend_xmin) DESC;
-[ RECORD 1 ]+------------------------------
usename      | DWH_NODI
state        | idle in transaction
wait_event   | ClientRead
backend_xmin | 47730267
xact_start   | 2022-08-25 21:03:02.961309
query_start  | 2022-08-25 21:05:32.27796
state_change | 2022-08-25 21:05:32.285729
now          | 2022-08-25 23:50:34.104552

You have set a statement timeout, but complain that a connection
(session?) takes longer,

Unfortunately, the statement and the table you posted don't match. Plus,
the table is very wide and almost illegible.

Please use option \x of psql to produce a better output.

Regards,

Holger
