ah, this looks very, very nice!
on page 5ff you describe the Postgres implementation, but the URL (page
5 bottom) is't complete -- can i find the files somewhere?
Included is a "tree_general.sql", but this seems not to be complete and
not the same version as the ps-file (First draft, may 6, 2000): in the
draft there is written about an base 160 encoding, tree_general.sql uses
base 159 encoding ;)


Ciao Alvar
