It will probably work. However, it is best to dump the old database
(7.4.x) with the new pg_dump (8.0.x)
> Is it doable to load the backup file using the psql (8.0.14) ?
Yes. psql is the preferred restore program for uncompressed file formats.
> Another question: Is it possible to upgrade 7.4.13 straight to 8.2?
yes, and also 8.3 as well. I'd recommend going to at least 8.2. 8.3
got rid of a lot of auto-type coercion that may break some poorly
formed queries. I'd recommend at least testing on 8.3 to see if you
can go to it.
