+  Check that the performance schema tables
+  have the expected structure.
+  Discrepancies are written in the server log,
+  but are not considered fatal, so this function does not
+  return an error code:
+  - some differences are compatible, and should not cause a failure
+  - some differences are not compatible, but then the DBA needs an operational
+  server to be able to DROP+CREATE the tables with the proper structure,
+  as part of the initial server installation or during an upgrade.
+  In case of discrepancies, later attempt to perform DML against
+  the performance schema will be rejected with an error.
