Because pg_freespacemap_pages() doesn't exist (and neither does the freespace map) in versions after 8.3. Had pg_upgrade existed at the time we removed the FSM, we might have taken a bit more care with what would happen in an upgrade situation ... but it didn't. You could do this via pg_dump and reload, in which case the missing functions would result in ignorable errors during the reload. If you want to do it via pg_upgrade, I think the most practical way is to drop the whole pg_freespacemap extension (ie, run its uninstall script) in your 8.3 installation, then do the upgrade, then install 9.1's version of the extension if you still want it. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
