There is a log_min_duration_statement setting in the postgresql.conf file that defines a minimum duration, after which the duration and statement will be logged. postgresql.conf 文件中有一个log_min_duration_statement设置，它定义了最短持续时间，之后将记录持续时间和语句。 If set to zero, all statements and durations are logged.如果设置为零，则记录所有语句和持续时间。
One should take care that using this setting does not consume too much disk space.应注意使用此设置不会占用太多磁盘空间。
