In postgreSQL, t= hat can be done at a session level, or at a general level (in the postgresq= l.conf configuration file)

Hi ,
We want to have controls around the DB resource utilizati= on by the adhoc user queries, so that it won't impact the application queri= es negatively. Its RDS postgresql database version 15.4.
Saw one pa= rameter as statement_timeout which restricts the queries to not run after a= certain time duration and queries will be automatically killed/cancel= led. However, I don't see any other options to set this at user level, rath= er it's getting set for all or at session level. So I want to know if there= exists, anyway to control the database resource utilization specific to us= ers?
Regards
Yudhi


This will set the timeout at session level. However, = We want to understand, if it can be done at user/role level, so that any su= ch adhoc user queries can be auto killed or cancelled after the set time.&n= bsp;

Or also at role/user level : 
ALTER ROLE <your<=
span class=3D"hljs-operator">-username=
> SET statement_timeout =3D '<time_u=
nit>';
