If a binary dump use pg_restore to restore the table you want to a scratch database then use dblink or copy to get that into a temp table in the database you want. If a text dump use sed (or an interactive editor) to extract the table data you want, load it into a temp table finally do an UPDATE ... FROM .... to fix the losses. I had to do this a few months ago. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
