Hi Rui DeSousa
Do I need to restart the postgresql service for log_checkpoints to make it active . I would like to enable this parameter temporarily and check it?
postgres=# show log_checkpoints;
log_checkpoints
-----------------
off
(1 row)
postgres=# show shared_buffers;
shared_buffers
----------------
60GB
(1 row)
postgres=# show max_wal_size;
max_wal_size
--------------
2GB
(1 row)
postgres=# show wal_buffers;
wal_buffers
-------------
16MB
(1 row)
postgres=#
Best Wishes,

Database is getting hung every day at 5AM. I found the below message from log file , Could you please help me , should I need to increase the max_wal_size value ?
Most likely. I would recommend enabling checkpoint logging to get a better understanding how often checkpoint are occurring, duration, and size in relation to buffer pool. Check for 'checkpoint starting’ and 'checkpoint complete’ in the PostgreSQL log files after enabling it.
What is shared_buffers, max_wal_size, and wal_buffers set to?
Why it say “incomplete startup packet” in the log.
