Hmm ... it looks like blob comments never have worked in tar format,
or not recently anyway. _LoadBlobs() runs off the end of the archive
file and then there's no mechanism for backing up --- not that that
would work anyway if reading from a pipe. I'm thinking of fixing it
like this (against HEAD, but the code hasn't changed much lately):

--- src/bin/pg_dump/pg_backup_tar.c Tue Oct 31 17:27:54 2006

lclContext *ctx = (lclContext *) AH->formatData;
TAR_MEMBER *th;
size_t cnt;

char buf[4096];
StartRestoreBlobs(AH);

ahwrite(buf, 1, cnt, AH);
}
EndRestoreBlob(AH, oid);
}
}

- tarClose(AH, th);
th = tarOpen(AH, NULL, 'r');
}
--- 726,745 ----
ahwrite(buf, 1, cnt, AH);
}
EndRestoreBlob(AH, oid);
+ foundBlob = true;
}
+ tarClose(AH, th);
+ }
+ else
+ {
+ tarClose(AH, th);
+ /*
+ * Once we have found the first blob, stop at the first
+ * non-blob entry (which will be 'blobs.toc').
+ */
+ if (foundBlob)
+ break;
}
th = tarOpen(AH, NULL, 'r');
}
Thanks for the report!
