This append feature did never work decently in gtar. Gtar did e.g. ignore the tar archive format of the first part of the archive and appended data in the current setup regardless of what the previous archive format was. BTW: given the fact that 8192 -rw------- postgres/postgres Nov 12 15:57 2014 global/pg_control is a file with 8192 bytes of data, it seems to be a bigger problem when this file disappears. Note that I can understand that there might be a +-1 offset error, but then the structural integrity of the new archive would be lost and the following file could not be seen.
