pg_basebackup: error: backup failed: ERROR: invalid segment number 0 in file ".DS_Store"
This one is pretty self explanatory. When running pg_basebackup on macOS it should probably be ignoring any .DS_Store files found inside data directories instead of transferring/processing them.
Steps to reproduce:
- on a macOS based pg server open a directory containing pg data files and set any kind of view options or move an icon
- this can also happen with inheritance, so even if you do not directly set these kinds of options on data folders, for example if a parent folder has a view option set when a new folder is created it can inherit the same view options, or if spotlight search sets up some metadata this .DS_Store may also be created
My workaround was to manually delete all of the .DS_Store files that the OS created and then immediately run pb_basebackup using the following method:
find <dir> -iname .DS_Store -exec rm {} \;
Some background on .DS_Store files:
