Review Comment:
So before the option was deprecated table names could either:
* Do no have `.` in their name
* Or have a single `.` in their name, in which case it was used to
identify the _database_
And now, independent of that property, table names may have a single `.` in
their name, in which case it was used to identify the _database_.
Then I guess it is not backward incompatible.
