Re: problem with pg_dump and pg_restore - Mailing list pgsql-admin

When I tried to use the 7.3.2 dump, and use 7.4.1 import, I had several
issues- mostly with data. I actually had to dump with the 7.4.1 dumpall
command, upgrade the DB to 7.4.1, and then everything imported correctly.

Hope this helps,
Corey

Why the schema/data separation? One important freedom you get when
combining
schema and data in the dumps is you can alter it after you imported the
data
and thus avoid cyclic dependencies where existance of one foreign key
mandates
the existance of another, which refers to the first one.

For now though, try eliminating all constraints from the schema dump and
ALTERing the tables after you imported the data.

Hope this helped,
