I am seeing something odd with retrieving contrib/earthdistance using
anonymous csv. If I do use the checkout command in the instructions
(cvs -z3 -d :pserver:anoncvs(at)anoncvs(dot)postgresql(dot)org:/projects/cvsroot co -P
pgsql) I get the earthdistance directory and its contents. But if I remove
the directory and use a cvs update command I don't get a refreshed copy.
Other contrib directories don't seem to work this way. Is this a mistake
on my end or is there some problem with how earthdistance is defined
in CVS?
