So in a way, you guys are saying one should never REVOKE CONNECT ON
DATABASE FROM PUBLIC?
All my DBs are not PUBLIC-accessible.
And inside my DBs, I try to revoke everything from PUBLIC
(USAGE ON TYPES, EXECUTE ON ROUTINES).
Nor do I use the public schema.
And I never use the "built-in" postgres database.
Basically I want all GRANTs to be explicit.
Given the above, I'd want to not provide access to the postgres DB too.
Yet have a way to discover which DBs I can connect to, from the "cluster only".
Kinda surprised you don't consider this a feature...give all of your databases UUID names and ensure that non-superusers must be told the databases they are allowed to connect to.
But feel free to work out a design and add it to the ToDo list for the v4 protocol. The use case seems reasonable and doable (on the basis of the replication protocol works).
