["James Pang (chaolpan)" <chaolpan@xxxxxxxxx>]

Hi,

It’s PGv13,  what’s relationship between max_wal_size and wal_keep_size ?  For example, wal_keep_size=200GB(to keep enough wal on disk pg_wal) ,   what’s best value for max_wal_size ?   we want to usage max_wal_size to control checkpoint .

 

Thanks,

 

James
