EUCA-8814 changed psql exec command log messages to debug (prevent constant status checks from filling up the info log) but also added some info messages on db startup/shutdown as well as some other operations (copy db, delete db, rename db) and more error log level messages when things go wrong.  These should not fill up the log as they are either errors or infrequent events
Merge branch 'dev/ethomas/EUCA-8814-2' into testing
