You can also try piping the dump through gzip and then restoring
using cat: pg_dumpall | gzip > db.out-`date +\%Y\%m\%d\%H`.gz cat db.out-`date +\%Y\%m\%d\%H`.gz | gunzip | psql template1 Sam From: pgsql-admin-owner@xxxxxxxxxxxxxx
[mailto:pgsql-admin-owner@xxxxxxxxxxxxxx] On Behalf Of Martin Povolny Hallo, I have some quite grave
problems with dumping and restoring large databases (>4GB of dump). I had 5 databases, 4 dumped ok, the 5th, the largest failed
dumping: I was unable to make a dump in the default 'tar' format. I got this
message: pg_dump: [tar archiver] archive member too large for tar
format I got over this issue by using the 'custom' format. Unfortunately later on I was only able to restore 3 of the 5
databases -- any of the 2 dumps that would get over 4GB in the 'tar' format
would fail. /var/tmp# ls -l dumps/ total 16294020 -rw-r--r-- 1 root root 742611968 2010-10-16 20:36 archiv1.dump -rw-r--r-- 1 root root 317352448 2010-10-16 20:37

failed and the 'bb.dump' which is in the 'custom' format, failed too. I got these messages: for the archiv5 in the 'tar' format: pg_restore: [tar archivÃÅ] nalezena poÅkozenà tar hlaviÄka v
STEX (pÅedpoklÃdÃno 100, vypoÄteno 34044) pozice souboru 7750193152 sorry, it's in my native locale, but is says "found a
corrupted tar header in STEX (expected 100, calculated 34044) file
position 7750193152 for the bb.dump in the 'custom' format: pg_restore: [vlastnà archivÃÅ] unexpected end of file 'vlastnà archiv ÃÅ' is again in my locale, it should be in
English "own archiver" Later I tried to utilize the -I and -i switches of
pg_restore to restore data that are in the archive behing the table that was
not restored. But got the same error message. The dump was created on postgresql-8.3
8.3.3-1~bpo40+1 from debian backports. I was trying to restore on this
version and later on using postgresql-8.4 8.4.5-1~bpo50+1 from debian
backports, finally I tried 64bit version
of postgresql-8.4 8.4.5-0ubuntu10.10. No change, still the same error
messages. I welcome any help and/or hints on this issue as I need to
dump and restore several large databases. Regards,
