        This is designed to detect collation
        mismatches to avoid data corruption.  Function

        reports the underlying operating system collation version, and

I just can't figure out what the user needs to understand about this,
and I understand very little of it.

We already had this feature for (schema-level) collations, now we have 
it on the level of the database collation.
