pg_upgrade loses all data

Release 6.5beta2

I've used pg_upgrade to import data from 6.4.2.

The tables are created correctly, as far as I can see, but the data gets
lost, so that no tuples are visible in any table I have yet looked at.
The data is actually present, because I can see it if I use `od -c' on
a table's file, but select * reports no rows.

Any clues, please?


NB: If this experience is repeated by others, anyone who had not backed up
his data separately would lose it all (if the tables are not repairable).
