Migration from 8.0 to 7.4...

Hi,

We've got a problem with postgres 8.0 (our own code is not ready yet for
the new driver) but a production database is already on postgres 8.0
(too bad, we didn't tested it enough...).

So we need to migrate back to postgres 7.4 and wait for a code upgrade.
Is there a possible way to do this ?

pg_dump output of 8.0 is not compatible with 7.4. But the output of
"pg_dump -a" seems to be compatible.
One solution would be to create tables with a 7.4 sql script. Then use
pg_dump to get the data from the 8.0 database and fill them in the 7.4
database. And finally restore all functions and triggers from a 7.4 sql
script.

Before testing this way, I would like your advise to know if our
solution has a chance to work, if there is a better way or anything...

Thanks for any help
