I got problem during restore of our database. The connection active and authenticated as became unauthenticated after restore restarting application fix the problem.

The user of the backuped database was the same in source-dest databases. I also have notice that dropping user and recreate it when a connection is active and authenticated, make far connection into an unauthenticated state.

there is a simple solution with JDBC pool configuration for this or is a server bug?
