gp_configuration_history

The gp_configuration_history table contains information about system changes related to fault detection and recovery operations. The fts_probe process logs data to this table, as do certain related management utilities such as gprecoverseg and gpinitsystem. For example, when you add a new segment and mirror segment to the system, records for these events are logged to gp_configuration_history.

This table is populated only on the master. This table is defined in the pg_global tablespace, meaning it is globally shared across all databases in the system.
