This patch stores the current catalog version in an internal table to allow us to verify catalog and code version match. When doing dump/restore people occasionally report very unusual errors and during investigation it is discovered that they loaded a dump from an older version and run it with a later code version. This allows to detect mismatches between installed code version and loaded dump version. The version number in the metadata table will be kept updated in upgrade and downgrade scripts.
