Using a separate filegroup, you can create one or more files on slower/cheaper storage and reduce storage costs for older data by explicitly placing the data on that filegroup. Creating a partitioned table And they will use CONTAINS and FREETEXT operators in SELECT queries to leverage the newly created FTI. It is a gigantic, and more importantly, completely open and free collection of over 200,000 data sets from the US Government. The older data can then be deleted. Continuous Archiving and Point-in-Time Recovery (PITR) At all times, PostgreSQL maintains a write ahead log (WAL) in the pg_xlog/ subdirectory of the cluster's data directory. Follow the 3-2-1 rule: There should ideally be 3 copies of the data, stored on 2 different media, with at least 1 stored off-site or in the "cloud".
