This tutorial shows how to do data migration, partition, and indexing in Postgres 10.
1. Migrate data directory
The dataset is quite large, and it will take up about 220GB of hard disk once loaded and indexed into Postgres. It is better to move the database storage to another large disk instead of the default (root) one. A Solid State Disk (SSD) is preferred for faster disk access.
(1) Check current Postgres data directory.
# log into Postgres sudo -i su - postgres psql SHOW data_directory;
