Point Nexus repo at a PostgreSQL database that has max_connections set to 200.
Configure the max DB Connection pool size in repo to be higher than 200.
Nexus Repo allows this setting change, but should not as it will eventually lead to certain database operations to fail.
Prevent configuring max db connection pool size greater than
or to an unreasonable value that conflicts with the actual configured value reported to be allowed by the database itself.
