In postgreSQL, that can be done at a session level, or at a general level (in the postgresql.conf configuration file)

Hi ,
We want to have controls around the DB resource utilization by the adhoc user queries, so that it won't impact the application queries negatively. Its RDS postgresql database version 15.4.

Saw one parameter as statement_timeout which restricts the queries to not run after a certain time duration and queries will be automatically killed/cancelled. However, I don't see any other options to set this at user level, rather 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 users?

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 such adhoc user queries can be auto killed or cancelled after the set time. 

ALTER ROLE <your-username> SET statement_timeout = '<time_unit>';
