The table has 20517267, and the datatype has 85286596. The type was introduced later
on, and added with
"alter table add". Maybe this is the problem?

Oops, I did not know this. What happens if I use the -C switch of pg_restore?
The man page says:
-C
--create
Create the database before restoring into it. (When this switch
appears, the database named with -d is used only to issue the
initial CREATE DATABASE command. All data is restored into the
database name that appears in the archive.)
But does pg_restore use template0 or template1?

No, I do not use 7.3cvs, this is version 7.2.1. But if this is fixed, it's not a
problem for me,
now I know how to restore the database, and 7.3 should not be too far away :-)
Thanks!
