Applications may use this to determine the version of the database server they
906+
are connected to. The number is formed by converting the major, minor, and
907+
revision numbers into two digit numbers and appending them together. For
908+
example, version 7.4.2 will be returned as 70402, and version 8.1 will be
909+
returned as 80100 (leading zeroes are not shown). Zero is returned if the
910+
connection is bad.
