Using which version? The one that came with 8.3? I'm suspecting that you used the one from 8.1.9, which would cause problems if you try to restore that in an 8.3 database. Also, 8.3.8 isn't the latest minor version, there's a (minor) security fix in 8.3.11 for example. Since you're still upgrading, now would be a good time to pick the latest minor release of 8.3. > Now, when we try to restore with psql, we get loads of errors and warnings: > > PROBLEM 1 > > psql:db03.ak1.sql:10155: WARNING: column "plan_status" has type "unknown" > DETAIL: Proceeding with relation creation anyway. > psql:db03.ak1.sql:10155: WARNING: column "plan_id" has type "unknown" > DETAIL: Proceeding with relation creation anyway. ... > From earlier reports on the mailinglist, I assume it is a view that has no explicit cast. No need to assume anything, the error shows you at which line the problem is, so you can verify whether the problem is indeed caused by a view definition. > What are the consequences of these messages for the system? > > Can I ignore the warnings and simply correct the views later?

These are probably real problems that you shouldn't ignore, especially if they're related to system tables. I think these are caused by using the "old" version of pg_dumpall or psql to create the dump. It's quite possible that the design of some system tables has changed between the two versions, and the "old" pg_dumpall/psql have no way of knowing about that. The newer versions have. > > PROBLEM 3 > > We get some messages that referential integrity rules (foreign keys) are violated. How can that be? This undermines my confidence in the system!! This would imply that the foreign key at one time did not exist, BUT WHEN IT WAS CREATED IT DID NOT COMPLAIN THAT THE RULES WERE VIOLATED....... These are probably the results of previous errors. For example, because of these errors some data wasn't inserted while later data depends on it, causing a constraint violation.
