Hello Tom
Thank you very much for the quick response.
I just realized the issue is caused by the tool, DataGrid, I am using. In DataGrid, when I close a tab, it does not actually disconnect from the database so it does not re-login when I open a new tab.
Again. thank you for the help.

Hmm, works for me:
regression=# create user test_user;
CREATE ROLE
regression=# ALTER ROLE test_user SET work_mem TO '50 MB';
ALTER ROLE
regression=# show work_mem;
work_mem
----------
4MB
(1 row)
regression=# \c - test_user
You are now connected to database "regression" as user "test_user".
regression=> show work_mem;
work_mem
----------
50MB
(1 row)
Perhaps you also have a setting at the per-database level, or
per-user-and-database level? The latter would definitely override
a per-user setting; I don't recall offhand whether per-database
overrides per-user. Look into pg_db_role_setting to see what
there is.
