PostgreSQL version: 8.1.3
Operating system: Mac OS X 10.4.1
Description: Problems Upgrading from 8.0.2
Details:

I'm trying to restore a database dumpall from postgres 8.0.2 to an 8.1.3
installation on the same machine but have encountered an error which has
resulted in some views not being recreated.

the problem is with the following statement in the dump file:

"CREATE VIEW wamp_product_extdesc AS
SELECT contenttranslation.franchise_code,
contenttranslation.contentobject_id,
"language".code AS language_code,
"language".uid AS language_id,
contenttranslation.info,
contenttranslation.graphic_url,
contenttranslation.contenttype_id,
contenttype.info AS contenttype_code
FROM contenttranslation, "language" contenttype
WHERE (("language".uid = contenttranslation.language_id) AND
(contenttype.uid = contenttranslation.contenttype_id));"

Which results in:
" psql:backuptoday.bak:5182: ERROR: missing FROM-clause entry for table
"language" "

Any help would be appreciated,
Dan
