Hello! just made a stupid move... upgraded a working system.... and without checking if the backup was ok.... so i end up with a debian system having upgraded to 9,1 without converting the database, and a scrambled backup which is totally unusable.... i tried to start the old tree with pg_ctlcluster 9.0 main start Error: could not exec start -D /var/lib/postgresql/9.0/main -l +/var/log/postgresql/postgresql-9.0-main.log -s -o -c +config_file="/etc/postgresql/9.0/main/postgresql.conf" : so i tried to copy the old 9.0 tree to a machine with a still working 9,0 postgres, but it stops with Starting PostgreSQL 9.0 database server: mainError: could not exec /usr/lib/postgresql/9.0/bin/pg_ctl /usr/lib/postgresql/9.0/bin/pg_ctl start -D /var/lib/postgresql/9.0/main -l /var/log/postgresql/postgresql-9.0-main.log -s -o -c config_file="/etc/postgresql/9.0/main/postgresql.conf" : ... failed! failed! so what can i do to extract the data of that tree and feed it into the 9.1 tree? thanks in avance! -- ciao bboett ============================================================== bboett@xxxxxxxx http://inforezo.u-strasbg.fr/~bboett/ =============================================================== -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
