PostgreSQL pg_dumpall error message



When doing a PostgreSQL database server upgrade, you first need to backup all of the databases because the format changes from version to version.

Postgresql documentation states you need to run the command:

1
pg_dumpall > outputfile

I ran this, and received the error message:

1
pg_dumpall: could not connect to database "template1": FATAL:  role "root" does not exist

So after some head scratching and googling without any results; I noticed that I had created a user for postgres; namely ‘postgres’. I sued to that user and ran the command – what do you know – it works fine! I’m glad that error message was so clear.

So, the thing that the documentation does not state – make sure you are running under the Postgresql user before running the backup command.

    HI,

    I’m using Centos 5.1x86_64bit and running mysql64bit also. I have activated the log-bin=mysql-bin on my.cnf but no logs are being generated as I need it for replication. Please help me out.

    thx a lot
