pg_statio_sys_sequences
A [statistics view showing IO statistics for each system sequence
pg_statio_sys_sequences is a statistics view showing IO statistics for each system sequence in the current database.
pg_statio_sys_sequences was added in PostgreSQL 7.2.
Usage
Note that as of PostgreSQL 14, no system sequences are defined so this view will always be empty.
