Okay, If I modify all the Sequences in the dump, everything works fine.
Is there any possibility to specify to the pg_dump to save the sequences
with the "old" type??? I mean not with No MAXVALUE and No Minvalue???

My problem is that the 7.3 database I cannot "update" it for the moment for
diverse reasons, and I would like not to modify any dump anymore.

A strange thing is that this type of dump already worked once....
