*I am trying to test the migration of postgres to 10 from 9.5*
*On trying in a test DB of size 490 GB in one postgres node it is taking
about 18 mins. The command I used*
*sudo -H -u postgres /usr/lib/postgresql/10/bin/pg_upgrade \*
* -b /usr/lib/postgresql/9.5/bin \*
* -B /usr/lib/postgresql/10/bin \*
* -d /var/lib/postgresql/data/postgresql0 \*
* -D /var/lib/postgresql/10/data/postgresql0 \*
* -o ' -c config_file=/etc/postgresql/9.5/main/postgresql.conf' \*
* -O ' -c config_file=/etc/postgresql/10/main/postgresql.conf' -k *
*Is there any faster way of doing this?*
