one of our heavy loaded postgresql servers regularly gives
LOG: statistics buffer is full
Sometimes those messages come when there is a load peak on the server, so it comes to my mind that it may be possible to improve performance by tweaking postgresql.conf to get rid of that full buffers.
We run 7.4.1 on Linux 2.4 (Dual Xeon 2,4, 3 GB RAM). pg_autovacuum is running.
postgresql.conf (tweaked parameters only):
shared_buffers = 20000 sort_mem = 16384 fsync = false wal_buffers = 256 checkpoint_segments = 6 log_timestamp = true stats_start_collector = true stats_row_level = true
Any hints?
