gs_tar
Background
After the backup is compressed using gs_basebackup, the primary data directory is written to a file named base.tar, and other tablespaces are named after their OIDs. The generated data file needs to be decompressed using the gs_tar command.
NOTE:
- Currently, the gs_tar command can only be used to decompress archive files generated by gs_basebackup.
- If a compression level is specified by gs_basebackup, a file ended with gz will be generated. In this case, you need to run the gzip command to decompress the generated .tar package, and then run the gs_tar command to decompress the generated .tar file.
