Hi,
checked the dump being made in backup file:
It includes this on top
SET statement_timeout = 0;
SET lock_timeout = 0;
SET idle_in_transaction_session_timeout = 0;
SET transaction_timeout = 0;
SET client_encoding = ‘UTF8’;
SET standard_conforming_strings = on;
The parameter transaction_timeout is weird here 
as
transaction_timeout was added in PostgreSQL 17.
stated here:
https://pgpedia.info/t/transaction_timeout.html
Need help 
Thanks !
Cheers,
Wurzelseppi
