PSU => Patch Set Update apprears to be specific bug fixes
PSE => Patch Set Exception
"Oracle provides patch sets that include generic and port specific
fixes encountered by customers since the base product was released"
and "The patch set exception bundles also include the fixes for the
CPU (Critical Patch Update), DST (Daylight Saving Time), PSU (Patch
Set Update) and Recommended Patch Bundles"
