Short answer is what Laurenz Albe posted.

Long answer is:

From:

https://www.postgresql.org/docs/current/view-pg-settings.html

select name, setting, context from pg_settings where name = 'work_mem';
name | setting | context
----------+---------+---------
work_mem | 4096 | user

user

These settings can be set from postgresql.conf, or within a session
via the SET command. Any user is allowed to change their session-local
value. Changes in postgresql.conf will affect existing sessions only if
no session-local value has been established with SET.

See page for the other possible values for context and what they mean
with regard to privileges.
