Operating system:   RHEL
Description:

We have identified an issue where predefined roles are not modifiable,
however a Dept. of VA security checklist requires that no roles have
unlimited connections. The Predefined roles have unlimited connections, is
there a way to modify these?

Solution 1: explain to your compliance department that it's pointless
to worry about the connection limit for a role that can't log in.

Solution 2: do a manual UPDATE on pg_authid.  This would have to
be done over after any major-version upgrade, though.

I think they mean the application connections from the UI to the backend, not backend SQL user login connection limits.

JAVA would be Hakari max_pool = 10 or something to that effect.

(I've been through this before), but you should check the requirement.

Also note that this is not by any stretch of the imagination a bug.
