Interesting.  This would work even if using --with-extra-version,
which is a good thing.

This comes out a bit strangely when using a devel build as this
appends -1 as sub-version number, becoming say 14.-1.  It may be
clearer to add back "devel" in this case?

Wouldn't it be better to add some perldoc to PostgresVersion.pm?
