Ok. I thought I had fixed this problem but now it is back. I separated my PostgreSQL backup job from my MySQL backup job and am now executing it as follows: su - postgres -c "/app/PostgreSQL/9.1/bin/pg_dumpall -h hostname -p 5432 -f /DBbackups/postgres/postgres.bkp_$backupdate -U backup" backupdate is being set prior to executing the command to the current date and time. It is working for a while and does backup some of the database until I get the following: 2013-08-02 14:04:38:426 EDT,"backup","dbname",21315,"hostname:40356",51fbf3a2.5343.401,"idle in transaction","2013-08-02 14:00:02 EDT,3/299,0,LOG,08P01,"unexpected EOF on client connection",,,,,,,,,"pg_dump" 2013-08-02 14:04:38.426 EDT,"backup","dbname",21315,"hostname:40356",51fbf3a2.5343,402,"idle in transaction","2013-08-02 14:00:02 EDT,,0,LOG,00000,"disconnection: session time: 0:04:36.044 user=backup database=dbname host=hostname port=40356",,,,,,,,,"pg_dump" 2013-08-02 14:04:40.981 EDT,"backup","postgres",21309,"hostname:40353",51fbf3a1.533d,47,"idle",2013-08-02 14:00:01 EDT,2/0,0,LOG,08P01,"unexpected EOF on client connection",,,,,,,,,"pg_dumpall" 2013-08-02 14:04:40.981 EDT,"backup","postgres",21309"hostname:40353",51fbf3a1.533d,48,"idle",2013-08-02 14:00:01 EDT,,0,LOG,00000,"disconnection: session time: 0:04:39.039 user=backup database=postgres host=hostname port=40353",,,,,,,,,"pg_dumpall" I have changed the hostname and the database name that was not the postgres database for security reasons. It looks like it completed the COPY statement for the table that it was backing up right before the error message occurred. I also do not see anything in the backup file that indicates what is happening. The Postgresql version is 9.1.9 and is running on CENTOS 5.9. Any help is appreciated.

The only thing I see is the error in the server's csv file. However, I got this to work by adding the following to the command line "su - postgres -c " and having the pg_dumpall command in double quotes. I was trying to run this as root but for some reason it did not like it.

I have only seen the server-side error you show when the pg_dumpall client had an error writing, due to permissions problems or disk space exhaustion, and the reason needs to be found on the "client" side, not in the server log. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
