+Applications may use this to determine the version of the database server they
+are connected to. The number is formed by converting the major, minor, and
+revision numbers into two digit numbers and appending them together. For
+example, version 7.4.2 will be returned as 70402, and version 8.1 will be
+returned as 80100 (leading zeroes are not shown). Zero is returned if the
+connection is bad.
