Обсуждение: problems dumping
Hello, I have a problem dumping with 7.2.3. When I do a pg_dumpall redirecting this to a file I have >40000 lines of schema and data. Running psql template1 < <dumpfile> the databases get partially created, i.e the schema is completely there but data even of the big tables is missing. The dumpfile itself has only 150k lines left. It used to work before I upgraded to 7.2.3. Any explainations ? I also did a " pg_dumpall -C -F p -f test2 -v". I can see the file test2 growing and I can see the schema an the data written in there. It all looks fine. When the command is finished the shrinks drastically and the data seems to be gone. Does anybody know the phenomena ? bash-2.03$ ls -al total 305588 drwxr-xr-x 2 postgres postgres 512 Oct 15 18:10 . drwxr-xr-x 3 postgres postgres 512 Oct 15 18:05 .. -rw-r--r-- 1 postgres postgres 156368896 Oct 15 18:31 test2 bash-2.03$ ls -al total 318772 drwxr-xr-x 2 postgres postgres 512 Oct 15 18:10 . drwxr-xr-x 3 postgres postgres 512 Oct 15 18:05 .. -rw-r--r-- 1 postgres postgres 163119104 Oct 15 18:31 test2 bash-2.03$ ls -al total 329556 drwxr-xr-x 2 postgres postgres 512 Oct 15 18:10 . drwxr-xr-x 3 postgres postgres 512 Oct 15 18:05 .. -rw-r--r-- 1 postgres postgres 168632320 Oct 15 18:31 test2 bash-2.03$ ls -al total 62 drwxr-xr-x 2 postgres postgres 512 Oct 15 18:10 . drwxr-xr-x 3 postgres postgres 512 Oct 15 18:05 .. -rw-r--r-- 1 postgres postgres 28684 Oct 15 18:33 test2 bash-2.03$ kind regards -andreas -- Andreas Schmitz - Phone +49 201 8501 318 Cityweb-Technik-Service-Gesellschaft mbH Friedrichstr. 12 - Fax +49 201 8501 104 45128 Essen - email a.schmitz@cityweb.de

It might be worth while dumping one database at a time and see what might cause the trouble. Or maybe it is the OS that truncates the file for some odd reason. What is the platform? Is you compress the dump on the fly, do you get truncated effect, too? (pg_dumpall |bzip2 -c >dumpfile) Hope this helps sorting out your problem. --Jyry C:-( C:-/ C========8-O C8-/ C:-(

This also happens with a compressed/gz file. The Platform is a SUN U2 with solaris 8. regards -andreas
