Hi all,

 

Following the discussion in message id - CAHGQGwFFMOr4EcugWHZpAaPYQbsEKDg66VmJ1rveJ6Z-EgaqAg@mail.gmail.com  , I have developed the patch which gives option to user to exclude pg_log directory contents in pg_basebackup.

 

[Current situation]

During pg_basebackup, all files in pg_log directory will be copied to new backup directory.

 

[Design]

- Added new non-mandatory option “-S/--skip-log-dir” to pg_basebackup .

- If “skip-log-dir” is specified in pg_basebackup command, then in basebackup, exclude copying log files from standard “pg_log” directory and any other directory specified in Log_directory guc variable. (Still empty folder “pg_log”/$Log_directory will be created)

- In case, pg_log/$Log_directory is symbolic link, then an empty folder will be created

 

[Advantage]

It gives an option to user to avoid copying of large log files if they doesn’t wish to and hence can save memory space.

 

Attached the patch.

 

 

Thanks & Regards,
