For the upgrade, you can use a newer version of pg_dump. I'm not sure if the parallel option would be available against a 9.1 server (but it's worth a try). I wouldn't try restoring that dump to a 9.1 server, just use it to upgrade to 9.4. > > > [root]# lsb_release –a > > > > LSB Version: > :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch > > Distributor ID: RedHatEnterpriseServer > > Description: Red Hat Enterprise Linux Server release 6.7 (Santiago) > > Release: 6.7 > > Codename: Santiago > > > > [root@CPPMOMA_DB01 even]# psql > > Password: > > psql.bin (9.1.2) > > Type "help" for help. > > > > postgres=# select version(); > > version > > --------------------------------------------------------------------------------------------------------------- > > PostgreSQL 9.1.2 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.1.2 > 20080704 (Red Hat 4.1.2-46), 64-bit > > (1 row) > > > > postgres=# > > > > > > > > > > Regards, > > Sachin Srivastava
