Hi All!
First time I see that the sum of written buffers:
3765929+878326121 = 882092050 = select
pg_size_pretty(882092050::numeric*8192) = 6730 GB
is bigger than buffers_alloc value in pg_stat_bgwriter view:
buffers_alloc | 20426161 = 156 GB
buffers_checkpoint | 878599316
buffers_clean | 0
maxwritten_clean | 0
buffers_backend | 3766409
buffers_backend_fsync | 0
buffers_alloc | 20426161
It's kinda mysterious... Any explanations?
Does it mean that the same buffers were written over and over again?
