Wait until the log is complete and closed before importing. For example, if you set it to 250ms then all SQL statements that run 250ms or longer will be logged.
These messages are emitted at LOG message level, so by default they will appear in the server log but will not be sent to the client. Also, on some platforms not using the logging collector can result in lost or garbled log output, because multiple processes writing concurrently to the same log file can overwrite each other's output. It is on by default. The numeric value is 1.
Only superusers can change this setting. And I am not aware of a good way to notify for enable success or failure. Type of log file Subfolder File name Outlook 2013 Outlook 2010 Outlook 2007 Outlook Autodiscover Solo olkdisc. The default is off. Unlikethis value is cluster-wide, so that all sessions will report timestamps consistently. Configuration Sample The following configuration example, when included in a Web. 
What is the Enable logging (troubleshooting) option? - This parameter can only be set in the postgresql.
On Windows, eventlog is also supported. Set this parameter to a list of desired log destinations separated by commas. The default is to log to stderr only. This parameter can only be set in the postgresql. PostgreSQL can log to syslog facilities LOCAL0 through LOCAL7 see , but the default syslog configuration on most platforms will discard all such messages. You will need to add something like: local0. This approach is often more useful than logging to syslog, since some types of messages might not appear in syslog output. This parameter can only be set at server start. Note: It is possible to log to stderr without using the logging collector; the log messages will just go to wherever the server's stderr is directed. However, that method is only suitable for low log volumes, since it provides no convenient way to rotate log files. Also, on some platforms not using the logging collector can result in lost or garbled log output, because multiple processes writing concurrently to the same log file can overwrite each other's output. Note: The logging collector is designed to never lose messages. This means that in case of extremely high load, server processes could be blocked while trying to send additional log messages when the collector has fallen behind. In contrast, syslog prefers to drop messages if it cannot write them, which means it may fail to log some messages in such cases but it will not block the rest of the system. It can be specified as an absolute path, or relative to the cluster data directory. This parameter can only be set in the postgresql. The value is treated as a strftime pattern, so %-escapes can be used to specify time-varying file names. Note that if there are any time-zone-dependent %-escapes, the computation is done in the zone specified by. The supported %-escapes are similar to those listed in the Open Group's specification. Note that the system's strftime is not used directly, so platform-specific nonstandard extensions do not work. If you specify a file name without escapes, you should plan to use a log rotation utility to avoid eventually filling the entire disk. In releases prior to 8. This parameter can only be set in the postgresql. On Microsoft Windows this parameter is ignored. The parameter value is expected to be a numeric mode specified in the format accepted by the chmod and umask system calls. To use the customary octal format the number must start with a 0 zero. The default permissions are 0600, meaning only the server owner can read or write the log files. The other commonly useful setting is 0640, allowing members of the owner's group to read the files. Note however that to make use of such a setting, you'll need to alter to store the files somewhere outside the cluster data directory. In any case, it's unwise to make the log files world-readable, since they might contain sensitive data. This parameter can only be set in the postgresql. After this many minutes have elapsed, a new log file will be created. Set to zero to disable time-based creation of new log files. This parameter can only be set in the postgresql. After this many kilobytes have been emitted into a log file, a new log file will be created. Set to zero to disable size-based creation of new log files. This parameter can only be set in the postgresql. However, truncation will occur only when a new file is being opened due to time-based rotation, not during server startup or size-based rotation. When off, pre-existing files will be appended to in all cases. This parameter can only be set in the postgresql. You can choose from LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7; the default is LOCAL0. See also the documentation of your system's syslog daemon. This parameter can only be set in the postgresql. The default is postgres. This parameter can only be set in the postgresql. If this parameter is set, the server will automatically run in background and disassociate from the controlling terminal. This parameter can only be set at server start. Caution When this parameter is set, the server's standard output and standard error are redirected to the file postmaster. There is no provision for rotating this file, so it will grow indefinitely unless server log output is redirected elsewhere by other settings. Even with those measures, errors reported early during startup may appear in postmaster. Valid values are DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1, LOG, NOTICE, WARNING, ERROR, FATAL, and PANIC. Each level includes all the levels that follow it. The later the level, the fewer messages are sent. The default is NOTICE. Valid values are DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1, INFO, NOTICE, WARNING, ERROR, LOG, FATAL, and PANIC. Each level includes all the levels that follow it. The later the level, the fewer messages are sent to the log. The default is WARNING. Only superusers can change this setting. The current SQL statement is included in the log entry for any message of the specified severity or higher. Valid values are DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1, INFO, NOTICE, WARNING, ERROR, LOG, FATAL, and PANIC. The default is ERROR, which means statements causing errors, log messages, fatal errors, or panics will be logged. To effectively turn off logging of failing statements, set this parameter to PANIC. Only superusers can change this setting. Setting this to zero prints all statement durations. Minus-one the default disables logging statement durations. For example, if you set it to 250ms then all SQL statements that run 250ms or longer will be logged. Enabling this parameter can be helpful in tracking down unoptimized queries in your applications. Only superusers can change this setting. For clients using extended query protocol, durations of the Parse, Bind, and Execute steps are logged independently. If you are not using syslog, it is recommended that you log the PID or session ID using so that you can link the statement message to the later duration message using the process ID or session ID. If logging output is sent to syslog or Windows' eventlog, the severity levels are translated as shown in the table. Message Severity Levels Severity Usage syslog eventlog DEBUG1.. DEBUG5 Provides successively-more-detailed information for use by developers. DEBUG INFORMATION INFO Provides information implicitly requested by the user, e. INFO INFORMATION NOTICE Provides information that might be helpful to users, e. NOTICE INFORMATION WARNING Provides warnings of likely problems, e. NOTICE WARNING ERROR Reports an error that caused the current command to abort. WARNING ERROR LOG Reports information of interest to administrators, e. INFO INFORMATION FATAL Reports an error that caused the current session to abort. ERR ERROR PANIC Reports an error that caused all database sessions to abort. It is typically set by an application upon connection to the server. It can also be included in regular log entries via the parameter. Other characters will be replaced with question marks? When set, they print the resulting parse tree, the query rewriter output, or the execution plan for each executed query. These messages are emitted at LOG message level, so by default they will appear in the server log but will not be sent to the client. These parameters are off by default. It is on by default. Some statistics are included in the log messages, including the number of buffers written and the time spent writing them. This parameter can only be set in the postgresql. The default is off. This parameter cannot be changed after session start. The default is off. This is off by default. This parameter cannot be changed after session start. The default is off. Only superusers can change this setting. For clients using extended query protocol, durations of the Parse, Bind, and Execute steps are logged independently. This behavior can be useful for gathering statistics in high-load installations. Valid values are TERSE, DEFAULT, and VERBOSE, each adding more fields to displayed messages. TERSE excludes the logging of DETAIL, HINT, QUERY, and CONTEXT error information. VERBOSE output includes the SQLSTATE error code see also and the source code file name, function name, and line number that generated the error. Only superusers can change this setting. Turning this parameter on causes logging of the host name as well. Note that depending on your host name resolution setup this might impose a non-negligible performance penalty. This parameter can only be set in the postgresql. Unrecognized escapes are ignored. Other characters are copied straight to the log line. Some escapes are only recognized by session processes, and are ignored by background processes such as the main server process. This parameter can only be set in the postgresql. The default is an empty string. The numbers are the process start time and the process ID, so %c can also be used as a space saving way of printing those items. This is useful in determining if lock waits are causing poor performance. The default is off. Valid values are none off , ddl, mod, and all all statements. PREPARE, EXECUTE, and EXPLAIN ANALYZE statements are also logged if their contained command is of an appropriate type. For clients using extended query protocol, logging occurs when an Execute message is received, and values of the Bind parameters are included with any embedded single-quote marks doubled. The default is none. Only superusers can change this setting. In the case of extended query protocol, this setting likewise does not log statements that fail before the Execute phase i. Temporary files can be created for sorts, hashes, and temporary query results. A log entry is made for each temporary file when it is deleted. A value of zero logs all temporary file information, while positive values log only files whose size is greater than or equal to the specified number of kilobytes. The default setting is -1, which disables such logging. Only superusers can change this setting. Unlike , this value is cluster-wide, so that all sessions will report timestamps consistently. If not explicitly set, the server initializes this variable to the time zone specified by its system environment. See for more information. This parameter can only be set in the postgresql. This lets you predict what the file name will be and know when an individual log file is complete and therefore ready to be imported. This is useful to protect against accidentally importing the same information twice. The COPY command commits all of the data it imports at one time, so any error will cause the entire import to fail. If you import a partial log file and later import the file again when it is complete, the primary key violation will cause the import to fail. Wait until the log is complete and closed before importing. This procedure will also protect against accidentally importing a partial line that hasn't been completely written, which would also cause COPY to fail.
