Carol,
If this is truely what you did, you are a very lucky person. You are always
supposed to dump the old database using the new versions
pg_dump/pg_dumpall. That way, pg_dump/pg_dumpall can set up the data for
any changes made by the newer version.
Just an fyi for those following this thread.
HTH,
