Why does the popup not show users(/roles/groups/whatever) in popup for $OBJECT(role)$ and show them for $OBJECT(login)$ (which actually seems to be a non-existent keyword in PostgreSQL)?

My wild guess, that's because of SA cross-platform support and the need to bridge the "naming" differences between different db types. Roles in PG are like logins in other systems if they're not "group" type roles. There are no users and standalone user groups. Groups are roles too with group attribute.

Yes, that's reasonable as an explanation why it has roles in popup for $OBJECT(login)$, even if the term 'login' seems not to exist in PostgreSQL. What does not make sense, however, is why not show them for $OBJECT(role)$ as well, which is what they are actually called there. You're correct that roles in PG are like logins/users when used to login, but they also behave like roles in other systems when they lack the canlogin property and are used for permission management.

Not showing them for $OBJECT(role)$ is somewhat counter-intuitive, imho.

Your point is very reasonable. I'm going to enter this a n enactment request. Thank you very much for your feedback.

Please update "Schemas (PostgreSQL)" query in the option to the following


Code:
SELECT
    nspname, 'SC', oid
FROM
    pg_catalog.pg_namespace
WHERE nspname NOT LIKE 'pg\_%'
   OR nspname = 'pg_catalog'

UNION ALL
   
SELECT
    rolname, CASE WHEN rolcanlogin THEN 'SL' ELSE 'SR' END, oid
FROM
    pg_catalog.pg_authid


After this change $OBJECT(role)$ should show group roles only, excluding logins. To show all roles with login permissions, use $OBJECT(login,role)$

You can tweak the query further to meet your requirements. Here SC is used for traditional schemas and users, SR - for traditional roles, SL - for logins
