Failed to validate connection org.postgresql.jdbc.PgConnection

When Canton and PostgreSQL are used together, the following warnings will appear every once in a while. How do I deal with them

@skylorna after the warnings appear, do things still function as they should, or is it not usable?

The node data will not be synchronized. The contract will not be visible for the node with warning. The data will not be synchronized until the node is restarted.
