System Catalogs
This reference describes the SynxDB system catalog tables and views. System tables prefixed with gp_ relate to the parallel features of SynxDB. Tables prefixed with pg_ are either standard PostgreSQL system catalog tables supported in SynxDB, or are related to features SynxDB that provides to enhance PostgreSQL for data warehousing workloads. Note that the global system catalog for SynxDB resides on the master instance.
Caution Changes to SynxDB system catalog tables or views are not supported. If a catalog table or view is changed by the customer, the SynxDB cluster is not supported. The cluster must be reinitialized and restored by the customer.
