Hi,

I think your suggestion is

SELECT set_config('statement_timeout','1000 s',false); -- enable timeout

--
-- DO SQL Statements here
--

SELECT set_config('statement_timeout','0',false); -- disable timeout

Am I correct? Moreover what can happen if another query runs on the same connection pool ?
I would limit the effect only on this specific query.

Roberto

This should work.
SELECT set_config('statement_timeout','1000 s',false);

The set_config function is quite flexible as can accept dynamic values.
More info here

I've used successfully to change the script timeout for each statement in
my maintenance scripts using a temporary table to store the deadline.

Kind Regards
Federico
