Hi!
>From your first message I was under the impression that pgAdmin shows one REVOKE ALL for every GRANT, i.e. all REVOKE commands at once. If that is not the case you may have found a bug in pgAdmin. Please ask on the pgadmin-support list or open a GitHub issue. Speaking of which, I found https://github.com/pgadmin-org/pgadmin4/issues/5926 which looks like the behavior you're describing. But this was already fixed in 7.2 and your original post says that you're using 7.2. Please check if your version is correct.
In pgAdmin 7.2 right clicking in table name and selecting Refresh does nothing.
Smells like a bug.
Right clicking in Tables and selecting Refresh worked.
