Woah ! That didn't work at all ! :-) First, the dumped reps.dump is 1.2MB
while the representations file is 1.8MB... then the reloaded representations
file is just 247kB ! And svnadmin dump then says "svn: No such representation
'4p9'"

db_load also had an error message at the very beginning:
db_load: Lock table is out of available locks
db_load: Lock table is out of available locks
db_load: Cannot allocate memory

but then continued happily... and left a mess, it seems :-)

I'll now the try the binary editor method ;-)
