Postgres Exporter pg_stat_bgwriter_checkpoint_write_time_total not working

Exporters and Metrics
1

Hi,

I installed postgres exporte on a postgres 17 server with the following collectors enabled together with the default ones.

    command:
     - --collector.postmaster
     - --collector.long_running_transactions
     - --collector.process_idle
     - --collector.stat_activity_autovacuum
     - --collector.stat_statements
     - --collector.stat_wal_receiver
     - --collector.statio_user_indexes
     - --collector.statio_user_tables

It seems not to be able to show the pg_stat_bgwriter_checkpoint_write_time_total metric.
Is there something I should enable on postgres or on the exporter to see that metric?

Thank you.
