We are getting this alert frequently "Required checkpoints occurs too frequently" on postgres version 11.8
The RAM of the server is 16 GB.
and we have already set the max_wal_size= 4096 MB min_wal_size= 192 MB.
There are more control settings for checkpoints, such as checkpoint_timeout. Check out the documentation and see if your set values make sense for your case.
I didn't realize this was answered, and as it was suggested, not a good idea to double post.
