wal buffer optimisation

[Fabrice Chapuis <fabrice636861@xxxxxxxxx>]

Hi,

It's hard for me to know if my Postgres 14 WALs configuration is optimal 

postgres [2854804]=# select wal_buffers_full from pg_stat_wal;

+------------------+

| wal_buffers_full |

+------------------+

|           910589 |

+-----------------

(1 row)

postgres [2854804]=# show wal_writer_delay ;

+------------------+

| wal_writer_delay |

+------------------+

| 200ms            |

+------------------+

(1 row)

I got some metrics from pg_stats_wal view:  15,702 buffers full in 24 hours and 1,243,890 writes in 24 hours, are these values indicative of a performance problem?

Regards,

Fabrice
