System catalog tables and views

System Catalog Reference : This is a reference of the system catalog tables and views of Greenplum Database. All system tables related to the parallel features of Greenplum Database are prefixed with gp_. Tables prefixed with pg_ are either standard
PostgreSQL system catalog tables (which are also used in Greenplum Database), or are related to features Greenplum has added to enhance PostgreSQL for data warehousing workloads. Note that the global system catalog for Greenplum Database resides on the master
instance.
