# 用户session退出时是否写入日志，默认off

# 一天内有多少个超过死锁时间的锁发生，默认是off，可以设置开启。这个可以区分SQL慢是资源紧张还是锁等待的问题

# 单位ms，超过1s为慢查询
# 其他日志
logging_collector      --是否开启日志收集开关，默认off，开启要重启DB
log_directory      --日志路径，默认是$PGDATA/pg_log
log_filename       --日志名称，默认是postgresql-%Y-%m-%d_%H%M%S.log
log_rotation_age   --保留单个文件的最大时长,默认是1d,也有1h,1min,1s,个人觉得不实用
log_rotation_size  --保留单个文件的最大尺寸，默认是10MB
pg_statement  = log_statement
# 参数值是none，即不记录，可以设置ddl(记录create,drop和alter)、mod(记录ddl+insert,delete,update和truncate)和all(mod+select)
  • 使用pg_ctl reload参数log_line_prefix可能不会生效，在psql下直接更改
alter system set log_line_prefix = '%t [%p]: [%l-1] user=%u,db=%d,client=%h ';
  • 生成html格式
pgbadger --prefix='%t [%p]: [%l-1] user=%u,db=%d,app=%a,client=%h ' postgresql-5.log -f stderr

SELECT pg_reload_conf();

shell脚本分析log

log_filename = 'postgresql-%a_39.19-%Y-%m-%d_%H%M%S.log'
