On closer inspection, pg_dump *does* quote "concurrently" ... if you're dumping from a 9.0 or later database. The problem is that it gets the index definition command from pg_get_indexdef(), which means it's relying on the server to do appropriate quoting, and a pre-9.0 server does not think there is any reason to quote "concurrently". There doesn't appear to be any fix for this that doesn't require a time machine and/or a lot more effort than it's worth. Suggest you rename the index in the 8.4 database. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
