 yesterday I had a problem with initdb. I set bad environment values
and initdb crashs (I set pglib path to PG 6.5.3 directory instead to
7.0 and initdb take this BKI old templates ... (initdb not check
BKI version and BKI files not has any version comments (TODO?))

 This patch add to the initdb --show option which show setting of all
initdb's values. It spare developers time if in setting is bug.
