Hello,
I'am a database administrateur and I get trouble to upgrade database postgres from 8.4.6 to 9.2.3. During pg_upgrade, I can't start the old cluster with parameter -c listen_addresses='' This syntax work to start the old cluster and to access to the database "/distrib/postgresql/app/chfdba/produit/8.4.6/bin/pg_ctl" -w -l "pg_upgrade_server.log" -D "/distrib/postgresql/data/chorus_formulaires/data" -o "-p 50432 -c autovacuum=off -c autovacuum_freeze_max_age=2000000000 -c listen_addresses='*' -c unix_socket_permissions=0700" start This syntax doesn't work to start the old cluster "/distrib/postgresql/app/chfdba/produit/8.4.6/bin/pg_ctl" -w -l "pg_upgrade_server.log" -D "/distrib/postgresql/data/chorus_formulaires/data" -o "-p 50432 -c autovacuum=off -c autovacuum_freeze_max_age=2000000000 -c listen_addresses='' -c unix_socket_permissions=0700" start But pg_upgrade use this "bad" syntax even I try to force -c listen_addresses='*' pg_upgrade -c -d /distrib/postgresql/data/chorus_formulaires/data -D /distrib/postgresql/data/chorus_formulaires/data/9.2.3 -b /distrib/postgresql/app/chfdba/produit/8.4.6/bin -B /distrib/postgresql/app/chfdba/produit/9.2.3/bin -o "-c listen_addresses='*'" more pg_upgrade_server.log could not connect to old postmaster started with the command: "/distrib/postgresql/app/chfdba/produit/8.4.6/bin/pg_ctl" -w -l "pg_upgrade_server.log" -D "/distrib/postgresql/data/chorus_formulaires/data" -o "-p 50432 -c autovacuum=off -c autovacuum_freeze_max_age=2000000000 -c listen_addresses='*' -c listen_addresses='' -c unix_socket_permissions=0700" start Failure, exiting I don't know how to workaround this problem ?
